Hands down the best shop! Amazing service took in my m340i and they did an amazing job with my downpipe installation and scheduling and pricing and just overall service from top to bottom was great. Special thanks to Ryan! read more

Took my G82 here for some seriously basic mods. Engine bay intake (they did install, but left off one of the O rings - even if it was missing PRIOR to them installing - a quality shop would let you know, get a replacement O ring, and make sure it's properly installed prior to handing your keys back). They charge a premium on labor and have high school / college kids doing the actual work. Springs - During spring install, they punctured my OEM auxiliary radiator and then proceeded to argue with me over providing me a replacement (yes the replacement part is a step up from OEM, but NO it wasn't something I planned to do at that point, and surely wasn't expecting to pay for it!) Exhaust - had them install a single midpipe. Left with an awful rattle at low RPMs, had to take it back a few days later, wait for 2-3 hours, and they couldn't figure it out. I did my own research and found valve controllers which fixed the problem - the fact they had no idea and sent me on me way just tells you how little these "techs" know and how poor the quality of work is over here. Reach out for an excellent referral I've been working with since. Much more reasonable labor, very transparent and honest, and actually does all the hands on work himself instead of subbing to junior techs. read more

I brought my MK6 GTI in for a diagnostic due to bogging down at around 2,500-3,000 RPM, I had replaced my High Pressure Fuel Pump and Fuel Pump thinking that was my issue. Turns out it wasn't and they figured out it was a Camshaft Position Sensor and the car is running perfectly after I replaced the part at home. As soon as I walked in the front I was greeted by the man at the counter, i really wish i remembered his name but he was super cooperative and answered any questions I had. I will definitely be bringing my car back here for any of my issues and tuning! read more

About a week or so ago I brought my porsche in for it's first oil change since I purchased it, this place was recommended to me by a friend, the staff was extremely helpful and friendly, and the work they did was fantastic. They even installed a cupholder for me while they had the oil changed as well. I will definitely be back the next time I need to have the oil changed again. read more

If you tell them you will be tuning your car somewhere else they get butthurt and won't help you out, will lie about other companies products that they know nothing about. They have one person who can test an ECU through the adapter, they don't sell it and if he's not there then they will charge 3 hours of labor + 250 for a 3 second process with the adapter. Was told multiple times id get a call back, nothing. No email back, and finally I was told to come in on Monday, Luis answered the phone and said they were gone ALL day long. They close the shop multiple hours early . Was a previous customer but not anymore. They are hiring , somebody teach them customer service . They also have maybe 3 employees it seems like. Shitty shop. read more

These guys really know what they are doing. This place is amazing. So glad I found a great and trustworthy shop to work on my vehicle. Thanks read more

Well tbh i dont know where to start i have an audi a8 i called and inquired about having it tuned nothing crazy just something to make my car a bit more responsive i spoke with a guy named luis who was just down right rude from the start. The very first thing i mentioned was im new to this and have very little knowledge but i would like to get a little something done and you guys were recommended. The response was well "why dont you just do some google research its easy" then proceeded to belittle me for not knowing about this kinda stuff was going to be a customer but after the snarky remarks and comments by luis and the bad mouthing other companies just because of a few comparison question is just immature and bad business read more

Today, 04/04/2022 I called to schedule an appointment for the second week of August to have my built 2012 Silverado tuned. Because I elected to do the build myself, they have refused to even schedule an appointment to see the truck and the work that has gone in to it. The truck will have: Whipple w140ax Supercharger kit Circle D 300mm Triple disc torque converter TSP stage 2 212/218 .550 114 LSA cam shaft Holley Longtube headers Walbro 450 fuel/E85 pump All new genuine GM engine management sensors MLS head gaskets ARP Head studs (over kill for 8 psi of boost) 100% New valve train (GM performance LS7 lifters, Hardened Chromoly pushrods, New rocker arms, TSP .550 Valve Springs) Heads will be machined by Zimmerman Racing Engines. All I ask is to be taken serious with an appointment, to have the work evaluated and when deemed excellent, the vehicle tuned. I sincerely hope this shop takes a different approach and realizes in an industry quickly becoming electrified, car enthusiast, such as myself will be their only future clientele. read more

John just tuned my E53 stage 1. As promised, you can definitely feel the difference. Will have 2nd stage done pretty soon. Need anything done to your car, call John. These guys are straight to the point and will not try to sell you some BS. Super great and friendly people. under promise, over achieve. Thanks John!!!!!!! read more

Best shop I've used so far. I have a performance car that I track, so competent work is critical. Everyone on the staff at Goodspeed is pleasant, courteous and knowledgeable. The work done on my Cayman was flawless. Just a great bunch of guys (and gals!). Highly recommend. Thanks to all! read more

The Goodspeed crew took in my older, formerly peppy but currently lackluster car with 100k+ and a broken turbo on it, recommended a performance upgrade package within the budget parameters I gave them, and gave my car new life. It's a ten year old car, but it's now more fun to drive than ever, and GTIs are usually pretty enjoyable as-is. The manager, staff and mechanics were all very focused on giving my car the best service possible, being thorough with both repairs and communication, all without cutting corners and keeping me close to my budget. I'm very happy with the end product. It should be noted that this is the second car that I've entrusted to them to transform, and they did a fantastic job on both of them. I get the impression they take great pride in what they do, which is very encouraging for the car enthusiasts that bring their cars there. My car is a sleeper at first glance, but now has a take-your-breath-away, slam-your-head-back-against-the-seat, upgraded turbo and top-notch tune that really unlocked the true potential of my hot hatch. read more

Had to bring my Benz in for tire change and brake replacement. The good speed team was able to get it done flawlessly and even had some suggestions for some other items they noticed I'd need that they had in stock read more

Friendly and very knowledgeable staff. They installed a jb4 performance chip and H&R lowering springs on a 2023 BMW X4 M40i. Work was completed on schedule and within a week of ordering as planned. See Yume for all you BMW needs! read more

Yume is very nice and provide great customer service. Goodspeed is the best shop in AZ. They've done everything to my car installing all my parts tune suspension. Tech did solid work. Just had coilovers, brakes and suspensions parts installed and everything was installed perfectly and rides great. I've been running on their build and tune for 3 years on my wrx and everything runs like new still 80k miles. read more

This is the best place to take your performance vehicle for mods or maintence in Arizona. Jon and Joe are very meticulous and have many years of experiance with highly modified vehicles. They got all the bugs out of my highly modified JDM swap Subaru that other shops could not fix. Clark Turner tuned it to perfection on their dyno.. This is the only shop in Arizona I take my performance cars. read more

My Subaru Wrx had a check engine light come on, I am new to the area and was looking for a reputable shop. Everyone I talked to were very friendly and helpful. They were nice enough to take the time out of their day to talk to me extensively about questions I had about my car. Very attentive and caring staff members at GoodSpeed. read more

My husband took his car here and ranted and raved on his service that he received! He said Jon took great care of him, was honest and to the point. Highly recommend!!! read more

I drive by their shop all the time in North Scottsdale and I decided to contact them and another tuner shop for my BMW m4. Dakotah responded right away with amazing speed and gave me options. The other shop took me a week to respond. He recommended I also add a heat exchanger to my package gave great reasons why. also their work was completed in 1 day! very happy with service and the performance of my BMM M4 read more

This place is the best, got my 840i tuned and it turned out great. Most recently took my x5m in to see if they could tune it. Unfortunately the ecu is locked so they can't do it at the moment but they said they would let me know as soon as it's available. In this industry, it's common for shops to over promise and tell you that they can do things that in fact they can't do. What I've always loved about Goodspeed is their transparency, if they can't do something the right way, they will tell you. Which I appreciate, couldn't recommend them enough!! Definitely a shop you can trust. read more

Nice guys, unfortunately not much of a military discount. The bad... I asked them to install a tune on Map2, they decided not to do that and then when I asked about it again they basically tried to talk me out of it. In the end my car is tuned to map1 which is not what I asked for or paid for. I'm sure there are better places out there. read more

Jon and his team performed a big repair on our 2012 Audi A4: the engine blew up and needed to be replaced by another one. Jon and his team did an amazing job in a short period of time. If you think you have a good mechanic, that would just be like a family doctor, but these guys are the true heart surgeons! They are incredibly knowledgable about the smallest details of how engines work and diagnosing problems. In our case the first engine that they ordered from a certified supplier did not live up to their quality standards. As an effect the supplier sent another engine with way less miles, for the same price, which they directly passed on to us. A-m-a-z-i-n-g! I would trust this team with anything and highly recommend them! Thank you guys! read more

Inquired about some work I wanted to get done to my car. Before they even knew the make and model they were already trying to up-sell me a tune, which I didn't need btw because my particular model didn't require it for the work I wanted to do. They didn't seem very customer oriented so I ended up going with another local shop. read more

Goodspeed is the best in the business by a mile ! Purchased a 2017 Camaro ZL1 and they were the first people I contacted. I won't have my car at any other shop in the valley. Jon and his team are ahead of the game and I'm happy I found them. The shop stays full because they take care of their people. Not sure if it's the right shop ? Call in and talk to them. All of their staff is friendly and happy to help. Can't say enough about this place. read more

Disappointed. These guys did a mediocre job installing an adjustable spring/damper set on my car, aka, "coilovers". I filled out the sheet to specify how low I wanted the car, front and rear, and they basically did whatever was easiest for them. I ended up with negative rake meaning that the rear was lower than the front. Way lower. Quite visibly lower. To the point where people asked me,"did you only lower the rear"? Goodspeed fed me some BS line about springs settling, blah blah blah. I finally took the time to correct it myself and now I see why they didn't want to fix it. Adjusting the rears is a pain in the butt! Tight fit, requires the lower arm to be unbolted to unload the spring perch and also the damper length needs to be adjusted. It's not fun, which I why I paid Goodspeed in the first place. Also, Goodspeed set the rear left just over one centimeter lower than the rear right. I finally got it adjusted properly on my own. I don't 100% blame Goodspeed. I mean, I should have pushed back harder against their BS excuses and made them set the height according to the sheet I filled out for them ahead of time. My bad. But wait, there's more. Shortly after the install, I started getting a weird clunking from the rear left. After checking everything I could, I took it to the dealership. Took them a while too, but they figured out that the lower bolt for the rear damper had come loose. Now I can't say whether or not it was Goodspeed's fault or not. I don't know if they torqued it down properly or not. And it isn't terribly unexpected for fasteners to require re torquing after a few hundred miles. So I don't completely blame Goodspeed. But that bolt doesn't really receive much stress, it isn't load bearing, so it really should stay the first time. Anyway, just a heads up. Inspect their work before you leave and demand what you paid for. read more

I love my car. Perhaps to an unhealthy level. I just have to put that out on the table immediately in attempt to add some weight to the following statements. Since I found Goodspeed, when I am working on my car, I look to Goodspeed first. I go here for my oil and filters (They've got Motul oil. Simply the best!) I went here when I had trouble with my air intake and they helped me sort it out. When I started getting a check engine light related to my turbo, I went in here with my suspicions of the cause. I talked to Jon for a couple minutes to describe the problem, he reached under the counter, pulled out a part and said "This is what you need right here." And guess what? He was right! I will continue referring my friends here, and going here for all my needs, most especially when I start doing more serious tuning of my car. I may live 30 miles away, but it's absolutely worth the trek. read more

Jon inspected an Audi I was considering purchasing and was able to point out some issues that I wouldn't have found myself. The inspection fee was well worth it, as it saved me thousands on future repairs (and gave me some negotiation ammo with the dealer). This is a great place, and I plan on returning once I make a purchase. Especially awesome that they do APR software! read more

Walked into goodspeed about 3 months ago and it was the best decision I have ever made. The service and quality of their work is next level. Everyone there is so passionate about what they do and their work shows it. Having never really modified my vehicles before a lot of this was all pretty new to me. Ive been working with Dakota and couldn't have asked for anyone better. He really goes out of his way to explain what needs to be done and how things work. Whenever they have my car I get frequent updates of whats going and where they are at with the install. They have done a lot of mods on my car over the past few months and Everything has been flawless. Cant wait for the next one! read more

I have been bringing my Mk6 GTI to these guys nearly since I purchased her in 2011 and have never been disappointed! Everyone I have dealt with through all of my modifications has been professional, friendly, informative, and has gone the extra mile to ensure I was happy with their work and products. From ECU to larger turbo upgrades I always look forward to coming in to Goodspeed for not only the modifications, but for the knowledge I gain by talking to any of the technicians, the sales managers, or Jon and Joe themselves. In short, I do not hesitate to give these guys (and gals too, Alli) my heartiest recommendation as a speed shop! read more

New to the area and found GSPL while searching for a reputable business to bring my 1992 Nissan Skyline R32 GTR in for a proper oil change. I stopped in and the team took the time to visually inspect the car prior to scheduling the car. They asked what kind of oil was in the car and had to special order the filter. After the oil change the car had developed a heavy leak, which was not unexpected, the car had a janky oil cap being used and it was end-of-life. I scheduled a follow-up visit where they modified and fitted a new oil drain plug. Ever since the leak has been eliminated. In all I am impressed with their knowledge, willingness, and fair price. I will be a repeat customer. read more

Goodspeed did a fabulous job on my 2013 Porsche Carrera 991. I had them install H & R sport springs which gave my ride the perfect stance. They also installed AWE sport exhaust. The sound is just what I was after. Not too loud and no drone. Can't say enough good things about Goodspeed Performance Lab. I will recommend them to all my friends and family. What a great team, Very knowledgeable and professional. All work was completed on time as promised. Thanks again! read more

Had the APR Stage 1 tune performed on my Audi A4. What a difference it makes, but the real difference makers are the staff at Goodspeed P. L. What an asset Jalene is to this shop. Her assistance and her manner on the phone prompted me to pursue this upgrade. Having found Goodspeed on the Internet, and having no preconceived position on what to expect, I proceeded with caution and I assumed I would consult other shops before proceeding. The time Jalene spent providing insight into the shop and its offerings won the day. With my curiosity piqued I arrived at the shop, but did so not fully committed to proceed. This is where Jon made the difference. His product knowledge and insight into the principles that support this upgrade appeared to border on encyclopedic. To his credit, he first pointed out issues that should be considered before deciding to do the upgrade. Only then did he discuss the performance advantages. This balanced approach, and his demeanor gave me the confidence to proceed. It took 5 minutes of driving to realize I'f made the right decision. read more

I just got my 2005 MK4 Jetta GLI 1.8T back from Goodspeed Performance Lab. I had and APR Stage I tune, APR Carbonio Intake, and an APR R1 Diverter valve installed today (Saturday, September, 2017). The car is a project that has 156K miles, just a toy that I wanted years ago but could never afford back then. Goodspeed again did a fantastic job on the VW. This is the third car that has been tuned and upgraded by Goodspeed for me and I am extremely happy everytime. I highly recommend Jon and Goodspeed. They checked out the GLI before they did the tune on it because of it's age and mileage to make sure it was safe for the car. This is an honest business that looks out for their customers. If you are in the VW/ Audi family definitely check out Goodspeed Performance. read more

great shop amazing guys at the front use to deal with tanner but now that he's gone i will be dealing with Jon, i bought a cts turbo down pipe for my audi and installed my self what a difference it made as well as these guys installed a APR intercooler and im very satisfied with all there work. thanks for the awesome service as always guys! read more

DO NOT TAKE YOUR VEHICLE HERE. I was scammed over $600 and they did NO REPAIRS on my vehicle. They had my vehicle for FOUR DAYS and did NO work on it when I had scheduled weeks in advance and put a deposit down for the parts and labor. They were not apologetic and have the worst customer service I have ever had in my entire life. They do not care about you, or your car. I spoke directly with the owner and he is very arrogant and greedy. They did not work on my car when they said they were, and did not provide any help when I was without a car for four days for literally no reason because they did not even start on my vehicle. Long story longer, they charged me labor fees for having my car. I will tell every single person I know about this, and I really hope this review helps you out. If you're looking for general maintenance, go somewhere else or they will scam you just like they scammed me. This is the worst customer service, and worst shop I have ever witnessed. read more

I recently bought a modded C63s from CA. Right away it threw a CEL. Needless to say I was furious. Then I was faced with where to take it for analysis. I called Weistec (car has Weistec turbos and tune) and they recommended Goodspeed. I took it there right away and spoke with John. I gave him all the history I was aware of...even though I know it was previously worked on by another local performance shop (the person I bought it from actually bought it from someone in Scottsdale and took it to CA). He agreed to look at it, despite not knowing the vehicles complete history and having at least two other performance shops tinkering with it. I was grateful he was willing to take on this project. Within a day he had found the culprit but warned me that this was simply a starting point and it could lead to the discovery of other issues, but was optimistic due to this being a common problem with this model car. I was given a projected date for completion and I left it in his capable hands. Due to some cancellations, John was able to work on the car earlier than I expected. He got the problem fixed but then ran into another issue. He was able to troubleshoot that quickly and repair it as well, all while keeping me posted and informed along the way. I picked it up a week before promised and couldn't be happier. The car rips, and runs like the angry beast it should with the list of mods it has. It's been three weeks since having it and no issues...other than me needing more rubber. I have a permanent smile on my face. This Benz runs like a champ thanks to John and Goodspeed. They were professional, up front, honest, and timely. They now have a customer for life. Again, thank you John and Goodspeed for being the rockstars you are. read more

Literally stumbled upon this place one day, I had to pull into a parking lot to figure out some directions and looked up and saw their office. Decided to stop in to see what they could do for my Ecoboost Mustang. Tanner really knows his stuff when it comes to the Ecoboost. I started out with a basic tune with the Cobb Accessport and I'll be going back to him for future upgrades for sure. He's really straightforward with what upgrades are necessary and not necessary for my car. I wouldn't even think about going elsewhere, check them out if you're looking for some more speed! read more

I have to thank, Good Speed Derick, Jon and some of the customers their today, Again These guys went above and beyond for me, got my Ultracharger tune today. From my experience if you need parts please order them from Good Speed, I had a horrible time dealing with ECS over parts I ordered from them. I will never purchase anything from Esc they suck. But enough of that, Good speed has every time not let me down and has on a few occasions went above and beyond. Great company great shop and a great group of people. Thank you again Good Speed for all your help making my Audi a super car. read more

I did some research on the top local tuners when I moved to AZ and these guys were top of the list. I had them do some porting and ceramic coating work, and Clark tuned my car to perfection for the crappy 91 octane AZ gas. I trust these guys to do it right and give good advice, and I keep going back. read more

Best performance shop in the Southwest for VWs, hands down! I've taken two of my GTIs in and their work is unmatched.

Jon, Joe, and the whole GoodSpeed crew rocks! They've performed performance modifications on my G37, supercharged E92 M3, my FJ Cruiser and my MK7 Golf R. Their attention to detail and professional staff are second to none! read more
