I took my ’71 C10 with an LS 427 to Ddtech tuning, and I couldn't be happier with the results. They completely fixed my timing issues, and the difference in the truck is night and day. The overall drivability has improved massively—it runs smoother, responds better, and just drives exactly how it should. I would highly recommend Ddtech to anyone needing their vehicle dialed in right.

Derrick was very responsive when I contacted him to schedule for in-person tuning and throughout the process. We got my 2011 CTSV tuned in no time. Derrick fixed quirks I had in my previous tune and now my car runs great. Honest and professional guy, would use again in the future.

I'll be honest Derek wasn't the first tuner I looked into because I was a little wary about remote tuning. I was going to work with another well known tuner, but what really sold me was the fact Derek was so quick to answer my emails. I knew if I was going to remote tune I wouldn't have to wait long for him to get back with me. I think I actually enjoyed the remote tuning experience because It was a chance for me to learn the use of hp tuning software. I would however say that the tune itself will at least get me down the road to the dyno for fine tuning to get the max performance with more adjustments to my VE and Spark tables. I feel that I at least got what I paid for as far as services provided.

What an incredible job. I had a bunch of issues with my supercharged chevy ss which was dyno tuned. Was recommended to reach out to derek. Amazing is all i can really say. Extremely quick responses, very knowledgeable and patient. And my remote tune from him feels way better than the dyno tune i had. Cant thank you enough, i will deffinately be recommending you guys to others.

Derek came in clutch with no notice or appointment and took the time to get my ctsv dialed in. Definitely a top notch experience

Prompt and punctual was my experience. Derek was able to handle any requests and answer any questions i had. Car runs they way it should. I cant stress enough how fast derek replys to emails, absolutely loved that.

100% recommended ! DD tech was far more than ready, Fast response, and great communication! Had my truck remote tuned and running smooth in no time. I can say his services are well worth every dollar.!

Very responsive and helpful. Worked with me while I worked out some issues with the car before we tuned. Car drives incredible and makes BIG power!

Derek is the man! I’ve been working with him since early 2022 and haven’t had any issues or complaints! He has amazing communication, he helps you out with any questions you have and throughly explains everything to you. He’s definitely your guy is you need any tuning done! Highly highly recommend! Just help helped me out with getting my ZL1 running straight and I’m beyond happy with how the car is running!

100% recommend to anyone or any shops that are needing a reliable and experienced tuning to tune their vehicles. Has been tuning vehicles for my shop for 3 years and have never had an issue. Great feedback and quick turnaround. Has tuned various GM(LS/LT), and MOPAR products for me.
