Testimonials

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.

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.

I’m so glad I listened to a friend’s recommendation and used DDTech to remote tune my CTS-V after giving it open heart surgery and some hefty upgrades. Such a great guy. You can sense his passion for what he does. So easy to work with. Response times were incredible. I never waited more than a hour for a revision. Derek was extremely patient with me. I was able to complete his tuning services at my own pace. This was key for me. Im very happy with the results of my recent remote tune. I will continue to recommend DDTech to others, and will never use a different tuner again.

Patient, knowledgeable, customer service oriented and FAST! Derek is in a league of his own and we would highly recommend trusting DDTECH to get the job done right!

I have managed a Diesel and Automotive performance and repair facility for 12+ years and in that time I have worked with A LOT of calibrators. I have to say, Derek is in a league of his own! Excellent work dialing in the calibration for the vehicle, exceeded beyond all expectations when it comes to turn around times and customer service. If you have any questions, you don’t have to fear the answer as Derek is very helpful and knows what it takes to get the job done. I highly recommend Derek and DDTECH and will be a continued customer of his!

car was running horribly and ddtech recommended me to a shop and they got me right cam installed and car is finally tuned and it’s dialed in great i feel in love with my car all over again!!

I was getting to the end of my 67 Chevelle Restomod build and needed to tune the LS3 with BTR Cam and 6L80e. I went around and around with some other tuner, and he could never get close to what Derek accomplished at DDTech. It did take a few files back and forth, but he was always accessible and replied almost immediately. In the end, he pushed the magic buttons, and I am totally enjoying it now. Even a couple of months after the tune was completed, I had a question, and he replied immediately. Derek is a rare find. USE HIS SERVICES. You will not regret it.
