    After being told, I don't need pistons over the phone.

    This is a follow-up review to the first review I left a few weeks ago, because I see the shop owner replied, but he isn't being honest. The shop owners explanation for the car possibly breaking a piston is that it was making too much power and the car already had too many miles. It's a 2013 Camaro SS, the engine is rated to handle 500-800 horses. After his tune the car was making 475. If the shop owner is so sure 200k was too many miles to apply performance parts to the engine now, why wasn't that communicated before he started the job? Leading up to the installation I asked the shop owner what does he recommend I do besides the mods I was already requesting and I asked if he could replace the pistons. Over the phone he told me I should get new lifters and a new timing chain and that I don't need new pistons. After the initial work was done I was told don't Rev the car over 2k and to drive on the street because the new clutch needed to be broken in up to 500 miles. The car was driven very lightly up until he tuned the car, a day later the engine blew. The morning before the engine blew I noticed a lot of thick gray smoke coming out of the exhaust that smelled like gas and the car was constantly back firing. Seconds before the engine blew there was a lot of backfiring. Besides not knowing what he's doing, he's dishonest with his pricing, hard to get in contact with and unprofessional. Do yourself a favor and find another tuner.

    Supercharger

    Contacted greg to install a stage 2 whipple supercharger gave me a reasonable quote and time frame. Got it done within the time frame and did a clean job installing it. Definitely having him do more work on the Mustang

    Excellent work done here at Racers Edge Tuning by Greg! Im a returning customer brought him my 04 Corvette he installed Supercharger Kit , Headers Exhaust , Tune and brought it back for New Clutch and more goodies ! No shortcuts taken he contacted the clutch company made sure everything was measured correctly and precise before installing and also kept me updated with the whole process would definitely recommend this shop he knows what hes doing!

    I took my 2019 Mustang GT into RET for a twin turbo, return style fuel system, and exhaust install. I was quoted the price from the beginning (most cost effective performance shop out of about a dozen I've called). Despite the hoops Greg had to jump through and missing parts from the kit, my quoted price was that price out the door. The install time was also extremely quick. I could tell based off the two occasions I visited to check on my car, Greg's work ethic was a very tedious and detail oriented one. He pointed out little things and went out of his way to make sure the job was done right. If you're looking for an honest, knowledgeable, and most importantly, a trust worthy shop to install performance parts, look no further. Racers Edge Tuning is one of Southern California's performance shop hidden gems. As always, thank you for all your help, Greg.

    Greg is One of the best in the business very knowledgeable and professional also a cool dude to chat about cars with I've been taking my cars to him for over ten years and not another shop around I would trust with tuning or working on my car like ret. His prices are very fair and he always helps where he can on recommending a path to take with the upgrades and what not. All of my cars tuned by him have ran perfect and strong day in and day out never any issues gotta say if you want a real tune or any performance work done hit up Greg he'll get your ride moving!

    The engine with the non CARB legal intake.

    I was helping out a buddy of mine with his 2011 Ford Mustang GT with a Ford Racing supercharger. The car got refereed and required a state inspection. I took the car to Greg and he helped me get the right intake (had the wrong one which was not CARB legal) and helped me by advising me to contact Roush who make the same kit but with a different head. He flashed my PCM with the stock code, replaced my spark plugs with the right ones, and then he put me in touch with the Roush folks who flashed my PCM with the CARB tune and I passed the inspection with flying colors! Although the car is no longer a bat out of he double hockey sticks, it is fully legal and runs great! Thank you Greg, I appreciate your help! My poor buddy had been trying to get his car fixed for two years and no one knew how to take care of the issue! If you have this issue, he is the man to go see!

    Well I had the option to really take May car anywhere I had even the option to go a cheaper route with a different tuner down the street

    Well I had the option to really take May car anywhere I had even the option to go a cheaper route with a different tuner down the street from Greg. I honestly did some research and was recommended by a GM tuner to the mustang man Greg. Funny thing was he said it was even weird to pay all up front having my car at another shop. Well lets just say the other shop didn't come through and he is also finishing my transmission install. Very quick response time and well seems to be A1.. I will for sure bring back my car for future upgrades..

    I had a lot of issues with my trucks engine and they helped me ordering the parts for my truck and after the tune my truck was running better then brand new

    06 Mustang at RET for tuning....

    Greg really is awesome at tuning and other work he does at his shop. Greg comes highly recommended for tuning by his peers. That's all I needed to know, although I've already been taking my 06 supercharged Mustang to Greg for years...... Happy customer and will continue to be while taking my Mustang to Greg at RET....

    Not enough good things can be said about Greg and his team over at RET. He has an excellent loyal customer base for 2 reasons; stellar customer service and workmanship. Also, Ed in the in-house parts department (Ed's Speed Shop) is the go to guy for Mustang parts at a fair price. Greg and his staff, and Ed, not only know Mustangs, but they live and breathe it. This place is legit.

    See all

    Took my 2016 GT PP to Greg at RET for a known IMRC failure issue and couldn't be happier with how he handled it.
