Customer Testimonials

Had Derek remote tune my V wagon. Couldn’t be more pleased with how it turned out. Great communication and quick turn around on revisions. Highly recommend letting him.
Derek is the man. He has been tuning my V2 for... 3 years now I think. When I first contacted him, dude was literally getting married the next day, still sent me a base map, and was tuning the car on his honeymoon as well. He answers fast, provides great help, and the tunes are phenomenal. Just finished up my 3rd tune with him after throwing a cam in the car and he turned it into an absolute monster!! If anyone I know has anything LS based, and are looking for a tune, I'm sending them to Derek cause I know he will take care of them 100%
Derek has tuned my CTS V3 for 3 years now. Just recently dialed my bolt ons and cannot see any other person tuning my car. He’s quick and responsive with any issues or concerns. Gets back to you fast. Definitely surpasses my expectations! Highly recommended. 5 STARS HANDS DOWN
The guy is amazing at what he does. Got my car driving flawlessly and made the drivability 100 times better within 3 days start to finish. 10/10. Very informative and helpful as well. Don't hesitate to get your car tuned by him
Easy to work with, simple instructions, very fast communication and process. Was able to tune my car within 24 hrs of starting. Highly recommend and if I need anything else will use again!
Derek Has done an awesome job in turning my ZL1. My buddy used him for his c7 and did amazing job to his car and highly recommended me to use him too. Whenever you need something or need to make any changes, Derek gets right on what you need and is there with just a text or a phone call away. It is hard to find someone good and doesn’t bs around. Will be using him for all my tuning needs. So if you are looking for a great tuner don’t hesitate give Derek a call you will not be disappointed.
I have owned a lot of cars in my life but Derek the owner has proven to me that American muscle still exists! I had him tune my c7 vette and recommend my friend in his zl1 to get tuned by him. Derek doesn’t disappoint when it comes to guiding me the way on how to use hp tuners. Very smooth process. Any issues I had he was one phone call/text away. I will be using him for all my ls needs. Great turn around time and a great product. 5 stars isn’t enough. Hit him up and don’t hesitate to contact him with questions!!!
Communication is absolutely incredible. More importantly his tunes are amazing! Via remote tuning he was able to tell me that I had a couple of sensors that needed to be replaced, abs other things that needed attention. And once I replaced them it fixed the issue that I was having. I had broke down twice, once with my family. I sent him a log of it running (barely) and he immediately diagnosed the problem for me, He didn't have to do that. It was after hours, which made his integrity stand out. But he most definitely is a 4am friend for those lucky enough to be in his circle. His tunes are incredible, his customer service is incredible. He goes way above and beyond a tune. From even the basics, like setting up my HP Tuners correctly, to helping me diagnose an issue that left stranded
Did a awesome job tuning my 2015 chevy silverado Z71. Has a BTR stage 2 cam. I had it tune before but was not running at full potential. After I left it was running prefect.was on point and running like a champ. He was help on all my questions and concerns.
Worked with Derek tuning a CTS-V. Fantastic tuner, super responsive, and very pleasant to work with. Unlike other tuners I’ve worked with in the past. Will be using his services again in the future.
