    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

    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.

    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!

    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..

    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....

    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

    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.

    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.

    This place is AMAZING!!! I was recommended this Auto AC…read morerepair shop by my best friend after her sister got her AC repaired here. The AC in my 2016 Honda Civic has given me trouble almost since I got it. The Honda dealership around the corner from my house was quoting me almost $4,000!! Memo, the owner, was extremely professional and was able to repair my AC the same day I took it in!! When I went to pick up the car, Memo showed me the parts that he replaced and what the problem was and even explained to me how it could have happened. He even took the liberty of replacing some of the rubber gaskets that were a little old and worn down!! Joselynn, the manager, was also extremely nice and transparent about the price when it went to pay. I am definitely going to bring my car back here if it ever breaks down again, which I don't think it will considering the amount of care that they took when repairing it. I highly recommend taking your car in if you have any AC problems.

    I highly recommend this shop for all of your auto repair and maintenance needs. Memo is incredibly…read moreknowledgeable, professional, trustworthy, and always transparent about the work that needs to be done. He has been servicing my vehicles for many years, handling everything from routine scheduled maintenance to more complex repairs. Most recently, I took my car to him after a dealership quoted me for a very expensive repair. Memo took the time to properly diagnose the issue and was able to fix it for a fraction of the dealer's estimate. What I appreciate most is his honesty. He easily could have upsold me on unnecessary repairs, but instead he explained the situation clearly and only recommended what was truly needed. I recently brought my second vehicle to him and received the same outstanding level of service. It's hard to find a mechanic you can trust, and Memo has consistently earned my confidence over the years. If you're looking for an honest, skilled, and reliable auto repair shop, look no further. Highly recommend!

    THE VERY BEST AUTO SHOP!!! I've brought several of my own cars here over the years and have also…read moresent friends and family, and every single time the experience has been great. What really stands out is the quality of their work, you can tell they genuinely care and don't cut corners. The paint matches perfectly, the bodywork is seamless, and everything looks like it did before the damage (if not better). They take their time to do things right, not just fast, and it shows in the final result. On top of that, they're easy to communicate with, keep you updated, and make the whole process feel stress-free. It's honestly hard to find a shop this consistent, and I wouldn't trust my car with anyone else!

    After getting hit and losing the back bumper, I went to 6 different shops for quotes, but Supreme…read moreCollision offered the best price! I knew I could trust Miguel from the moment I met him. He genuinely cares about his clients and went above and beyond! He worked seamlessly with the insurance adjuster and even helped me secure a car rental, making the whole process much easier. Not only did he fix my main concern, which was the back bumper, but also gave me a great price on other aesthetic concerns. As a bonus, I asked if he could help with the fading paint on the top of my car (given that I would be paying out of pocket for this part). He agreed to paint it and gave me an incredible deal that I couldn't resist! His team worked so much faster than I expected, all while staying in constant communication and maintaining excellent quality of work. I couldn't believe how great my car looked when I got it back! My car literally had a makeover! It looked so much better than it has in yrs. The color match was perfect, and the brand-new original bumper was installed flawlessly. I give Supreme Collision an 11/10 and highly recommend them to anyone in need of car repairs.
