10/10-Downpipes & Tune on my Audi S8. Dyno pic attached showing huge gains over both stock and my previous tune from elsewhere. Andrew is incredibly responsive, communicative, and was my sole point of contact from my initial call into them asking for advice based on my goals for my vehicle all the way until I picked it up. My car was fast before and had a plug & play tune, but is now at another level after their custom tune. Absolutely worth the drive from North DFW. Will absolutely work with them again. read more

I'm posting my review here because a few posts in this group led me to try Cedar Performance, much to my DISMAY. BUYER BE WARNED! Do not let these guys tune your vehicle. Matt has been very difficult to deal with. Responses take at least 2 weeks and sometimes longer if at all. Most times my messages are left READ, with no reply. When I do have to get ahold of him, I have to reach out to two whatsapp numbers, Facebook, instagram, call his shop, call his wife, to get any kind of reply, if any at all. We spoke before the tuning process and he assured me that responses were sent within 24 hours unless its the weekend, then when I complained about the lack of response, he said 2 weeks is perfectly acceptable for a reply and, "It's no skin off my nose if you go to another tuner." I had an easy stage 2 93 tune for my M6, a year later it's still not completed and unuseable. I ended up deleting it all together and take the $1000 loss. I messaged him telling him how displeased I was with his service and was moving in another direction for my tune, then 2 weeks later a random tune update pops up from him. This new update made the car undrivable, plus again when I told him about the issue, left me on READ with no reply, no update, nothing. I believe the last update was sabotaged. Don't waste your money here, go with F80 Paul for results and great support. I trashed Cedar's tune and the car performs much better on an OTS map, and F80 pauls tune is a night and day difference between both. read more

If you own a BMW and you're looking to get any work done whatsoever, Cedar Performance should be your one and only stop. Matt and Daniel are GREAT! At first, I took my 7 Series to Jotech Motorsports to have Ghost lowering links installed. They did just that and slammed the car - didn't even adjust the links. Had to have them removed otherwise I was at high risk of destroying the air suspension. Took my car to Cedar and Daniel set it to the perfect height. During that same visit, I had Matt code my car for the Alpina cluster and more. A week later, I brought my car back in for Stage 1. Few weeks later, I brought it back in for downpipes and Stage 2. Couldn't be more happy. Great shop, strong work ethic and very knowledgeable. Derek Alexander, 36 read more

Had them unlock my f82 m4. Super friendly and quick. Definitely recommend for bmw work.

I didn't get any work done by Cedar Performance. I had an appointment to get my DME unlocked and the place was a ghost town. There was a FedEx final delivery attempt notice slip on the door that was dated the same day as my appointment. Spray paint on the building front and overall not a very inviting place that would make a new customer feel comfortable. After calling their outsourced answering service I learned the shop was closed that day. The owner was out of town and Matt had a family emergency. What about the final delivery attempt notice? Is anyone ever around? When the owner is gone, does business responsibility fall short? Lots of questions rolled through my head. The answering service promised they could do it the next day but I opted out. What a blessing in disguise because I found a bad ass Bimmer Only place in Dallas. Take my review for what it is, it was my introduction to Cedar Performance that was sour from the second I pulled up. I couldn't recommend them to anyone... read more

Matt & his small team really do a great job tuning cars & solving difficult problems. He even went above & beyond to rebuild an engine for me, although that is not his typical business. His technical knowledge is unusually impressive, & he makes helpful suggestions along the way. He'll get you tuned up & you'll be setting the road on fire before you know it!! read more

I went to Cedar Performance for over two years. In the beginning, Matt was friendly and helpful. He influenced me to buy a number of performance parts for me car. "Now you just need this..." and "Now you just need that and it'll work better" and eventually over time, my car got to the point where few people in town could work on it and I became dependent on him as a mechanic and tuner. Over time, it started taking him longer and longer to finish work on my car when I would bring it to him, especially if I paid him up front, to the point where it was in his shop for weeks at a time for things that seemed like they should take alot less time. I noticed other people were complaining about that as well. He even mentioned to me once that there was talk of him being sued for this. It was certainly the case for me that my car was there for very long periods at a time. My motor eventually failed, and had to be replaced. My original thought was to buy one from a company, but Matt said he could do it and quicker. It took around 8 months for him to build the motor and get it in my car. Unfortunately, I made the mistake of paying him "up-front" for almost everything. I got frustrated a couple times, and Matt became more and more rude and unprofessional to me over time, often making comments such as he was "sick of my car". I'm attaching some text messages he sent me. To me, this was unacceptable. All I wanted was for him to fix my car and get it back to me in a reasonable timeframe. When I picked it up, however, it had issues and was not running right. I asked him if, this time, he could let me know when I could drop it off on a day he would actually be able to work on it, as opposed it sitting around the shop while he worked on "higher paying jobs" as he put it to me at one point. After dropping it off, it was there almost two months. When I picked it up, it still had all the same issues it had when I dropped it off, except for the suspension squeak that he fixed. I had had enough at this point. I desperately searched around for a place I could take my car, and finally found a great place. I have spent literally thousands of dollars to have my car fixed since I got it back from Matt. In the process, it was revealed that his work was sub-par. For example, the air filter was literally half way off the intake pipe. This is very dangerous because it could allow water to get into the engine and perhaps bend a rod. There were cables laid on top of the engine. The catch can wasn't even hooked up, and a few other things too. We also found out that the spark plugs were bad, something I asked him to check when he was trying to figure out why my car was missing, at which point he became insulted that I even asked such a basic question. I'm attaching photos to demonstrate what I feel was poor quality work from Matt at Cedar Performance. I do not recommend Cedar Performance, based not only on what, in my experience, was poor quality work, but also very long times that mine and other customers cars were in his shop as he worked on other cars and I waited and waited patiently. I won't be returning to that shop, and won't recommend anyone else go there either. read more

We also found out that the spark plugs were bad, something I asked him to check when he was trying to figure out why my car was missing, at which point he became insulted that I even asked such a basic question. Those spark plugs are why the motor was missing. Photos do not lie, as to two other mechanics who witnessed and can back up what is in the phots below; one of them was an air filter not even hooked up all the way, cables laying across the motor, large plastic pieces not even connected and simply unattached on top of the engine etc. He claimed my car made good power on his dyno and didn't miss however that is simply not true at all, as proven by the spark plugs pulled by the other shop right after taking it to them. Matt once made the comment "Unfortunately the n54 engine has a host of natural issues" and my car was "plagued" with them. This simply is not the case - the reality is, he didn't even check basic mechanic issue such as spark plugs, and whether he installed port injection correctly and literally spent weeks trying to figure out why my car was missing and going into limp mode. However, another shop was able to quickly resolve these issues within a few hours. The ONLY reason I stopped taking my car to Matt and Cedar Performance, is due to the very long wait times (two mechanics told me someone came to them after having their cat at Matts for AN ENTIRE YEAR); any claims by Matt of personal problems on my end are simply lies and completely untrue. I do not recommend Cedar Performance, based not only on what, in my experience, was poor quality work, but also very long times that mine and other customers cars were in his shop as he worked on other cars and I waited and waited patiently. I won't be returning to that shop, and won't recommend anyone else go there either. read more

Matt is a great guy and awesome mechanic, even when under BMWs "free" service plan I took my car here rather than deal with the monkeys at Classic BMW. He goes the extra mile for his customers and is incredibly knowledgeable, honest and extremely reasonably priced. Cannot reccomend highly enough! read more

My whole experience was pretty frustrating. It was difficult to get updates, they left my AMG GT R with sticky residue that was very difficult to remove on both sides of my hood. They left my hood misaligned, didn't deliver the promised horse power the first time, and the second time -never finished my tune. My check engine light still comes on when I floor it -they are aware of the problem and said they would fix it but I have not heard back in months - Maybe they think I've forgotten about it. read more

The boot latch of our 2011 MINI was broken and we've bent walking by this new business every day when we walk our dog, so I stopped in yesterday to get a quote to fix it. It was substantially less than the dealership to fix, done the next day and SUPER friendly. We will use them for all our auto needs going forward. So happy to have a new business in The Cedars as well. read more

Great customer service. Have had my GS350 & CL550 worked on here over the past several years. Matthew is very helpful and knowledgeable. Definitely the kind of mechanic and shop owner you can trust. Can't wait to get my E63 M6 in there. read more

Used to think this place was the "best" but after experiencing other shops came to realize this shop is just hype, especially on social media (Cedar Treatment). Had work done here 4 times. The First job was done good but the more times I visited, the work became more inadequate NOT to mention the ending bill was always more than the price quoted or listed online. Here are my list of experiences: 1st visit: Down pipe install, Good. 2nd visit: Exhaust install, received same day but tips were crooked and was told if I wanted them to be straight that I would have to come back & more labor would have been charged. I Chose Cedar Performance because of their self-proclaimed Moto on site/social media of "doing things right the first time" the "Cedar Treatment".. I let this go & was understanding. 3rd visit: FMIC, CP, & powder coated oem wheels. Received in 2 days. Pre-payed during pick up to get spark plugs replaced following week. Everything was good until I encountered a problem that the vacuum line from the Charge pipe keeps popping off under high boost. E-mailed the owner about my problem & to schedule to get my spark plugs replaced that I ALREADY PAYED FOR. No reply was received from the owner. (I have proof and documentation of all this) It seems like he won't work on the car unless if I were to spend more money. Thus breaking his promise of replacing the plugs the following week after this visit. 2 weeks still had no reply. 4th visit: After a month. MY mistake of trying a more aggressive tune, too much for an N20. My engine blew. Stuck on the side of the road, called the shop. Got quoted on the phone "out the door" price. Received call from the shop after 3 days. Was told (Wednesday) if I were to get the engine (6month engine warranty/1 year install warranty) through the shop the job would be done in 2 days, EXCEPT the catch was the cost through his supplier was more than what he quoted. After (Friday) the first deadline had been missed. Owner had mentioned that he had to attend to a family matter and I was understanding to it. Gave me a deadline the following week (Tuesday-Wednesday). Missed these days as well. The owner has mentioned that they work on my car 4 hours a day since the day I gave consent to buy the engine from him. Told me it will be ready (Saturday) I gave the shop a call the day before the given date and was told it will not be met. At this point it has been almost 5 business days. The next following week has come and received the vehicle Tuesday night on Thanksgiving week. The coding that was "free" was not done, me and the owner talked about this through email. He said he forgot. Received the vehicle with oil and shards of metal from the old engine still on the subframe/belly pan. Owner addressed the issue regarding oil residue from my old engine and promised to have me drop by in a week to get it cleaned up. I accepted delivery as I needed a vehicle for work. Drive home seemed good. Next day, e-mailed the owner and told him that there was a small puddle of oil when I left for work in the morning. He replied, he figured that would happen because of the oil from the old engine and not to worry. I trusted him. During lunch the car was sputtering and kept stalling during acceleration. Called the shop and he said to take it in Friday morning as we had a holiday the next day. He recommended to unplug the MAF sensor to prevent the car from stalling to at least have the car and be able to drive for groceries. The next morning on Thanksgiving the car asked for more oil. I look under and the oil puddle was larger than before. Took it upon myself and took the belly pan off and see what was going on. Oil seemed to leak everywhere. Took pictures and videos, documented the work done. Took it Friday morning. Received the call Saturday that my turbos are blown and as to why I was leaking oil and smoking profusely. At this point I didn't know what to do because prior to dropping the new engine, the owner mentioned that all other mechanical parts looked good and that this job would have no hiccups. At this point the owner "adviced" me to trade-in my vehicle.. Upset over the situation, I took my car home to look at my options. After a week had it towed to a new shop. Two weeks later finally got a call and he offered to replace my turbo for a used one off eBay. My car was already in another shop, owner offered to get it towed and cover expenses but after this "experience" I was reluctant to even bring the car back. Now, after receiving my vehicle from the NEW shop, made me realize that there are definitely better shops out there. I was just genuinely blinded by Cedar's social media hype of track cars. Anyways just sharing my experience, as a customer from experience.. quality control needs to be checked especially if mechanics in training are the ones practicing on customers vehicles & owner needs to learn better customer service than being a hot head read more

Even though this shop doesn't work on Lexus but mainly BMW's Matt sure did take care of me. I had an issue with my transmission and I did not have a car to drive to work and it happens that my car broke down near his shop. I have to say he is a very great guy that would help you get right back on the road. I can see a great future for this shop! read more

Great service! Matt, the owner, is detail oriented. The shop is always clean and neat. He even stayed after hours to finish working on my car. read more

Have a project C450AMG. Had been looking around and reading review after review of a few shops in DFW. Had been burned by shops who didn't value my time nor investment in the past and currently. Came across Cedar Performance and figure I'd give them a try. Matt was very personable and knowledgeable and most importantly honest about what I was looking at as far as time, cost and work. Just had a AMR stage 2 done and had Matt install an AWE track exhaust, weistec downpipes, custom carbon fiber dual exhaust tips, A service, and lower the car with H&R springs. He knocked it out in under 48 hrs and communicated with me the whole way through. Aspects of a quality shop. Pricing was reasonable for the clean professional work performed. Car rides great and sounds like a beast! Glad I gave them a shot and will continue to take my car there for more work. Try them out I am sure you won't be disappointed. Thanks Matt! read more

My car runs worse than it was b4 I dropped check engine light is on and now he refused to fix the issue he has caused taking him to court. Do not go to this place go anywhere else literally let a homeless man work on it b4 you let Matthew touch it. read more

Matt at Cedar is the man. He was really easy to work with and knowledgeable about all things M. Had some things coded by him on my F80 and it was quick and painless. We spent some time looking into GTS and CS coding and ended up coding those options into the F80. It has completely transformed the car. Cedar is the go to M shop in DFW and everyone knows it and goes there. He even had Ms from Houston there because he the most trusted. Will definitely go again. read more

I currently own a 335i and I only take my car to Cedar Performance. This is an AMAZING shop. They have helped me with both general maintenance and modifications. Matt (the owner) is always helping me out with exactly what my car needs and cuts out all the BS other shops have tried to sell me. The shop has very great prices especially when you consider just how much BMW maintenance is at another shop or the dealer. Recently the shop stayed open for me after hours to help me with some spark plugs and a few other things. They even stayed behind a little extra after this just to talk cars and answer some general questions I had about my car. The staff is very friendly and professional when working on your cars. As someone whose lived in all the major cities across Texas I can hands down say this is the best shop I've ever been to. read more
