Very helpful, replies super quick and whenever I want some changes done he always gets it right and super quickly made my truck feel amazing 100% will keep getting my vehicles tuned by Derek

Derek turned my FBO corvette from “fast” to “…I need to buy drag radials now” fast! All while keeping stock manners. You’ll never know how rowdy it is until you hit that gas pedal. He’s the man! Highly recommend!

Highly recommend DDTech Tuning\. The communication is unmatched — constant back and forth throughout the entire tuning process, answering questions, reviewing logs, and making sure everything was dialed in correctly\. The difference in the car is night and day compared to my last tuner\. It feels stronger, more responsive, and overall much better put together\. You can tell he actually takes the time to get the setup right instead of just sending a tune and calling it done\. Definitely glad I made the switch to DDTech\.

Very responsive, helpful, good communication. Also got my car running perfectly no other tuner got it running as good

Derek is not only a great tuner, his customer service and response time is EXCELLENT. I gave him a rundown of my platform and build/mods list and he delivered a safe and awesome running turbo truck! Id recommend Derek to anyone that needs a solid tune no matter how in depth the build is. Thanks again for the help!

Great Experience! Can't be more happy with the tune. I would send Derek a log and in no time, I would have the next tune. Even on weekends. Highly recommend. Next car I need tuned, I will be calling Derek. 2015 Chevy SS with LSA and Cam.

I just ls swapped my 1993 Chevy 1500 and came to him for a remote tune and let me say I got that and more. Derek went above and beyond throughout the process by being patient with me and helping me diagnose some issues along the way. On top of that his response time is incredibly quick. I definitely recommend him and will not hesitate to come back with future projects.

Derek and DDtech nailed the tune on my LSA converted 5th gen Camaro . Communication has always been spot on and any issues or concerns fixed immediately.. I wasted money on another well known tuner out of Texas before I found DDtech, wish I would have found DDech first and saved a bunch of $ and headaches.. Do not hesitate to go with Derek, he's a stand up guy and stands behind his product.

Derek don’t mess around, he takes minutes to respond and is very simple and straight to the point. car is running excellent and shifts fantastic. would highly recommend for remote tuning and is probably even better in person.

Derek Tuned my cammed 06 GTO. Car runs and drives perfectly and makes more power now. Excellent response times from him. My first time using HP tuners and he wrote out instructions on what I needed to do (very helpful). Definitely having him do all my tuning on LS cars. Derek is very good at what he does.
