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\.

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 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!

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.

Car was running ok, but felt like it lacked power especially with a few upgraded parts. Contacted DDTECH and he got the car dialed in within a couple days. Pulls strong and drives like factory! Thanks again!

Absolutely blown away by the tune on my Camaro. The car feels like a completely different animal , stronger, smoother, more responsive and dialed in perfectly. The entire remote tuning process was easy, communication was excellent, and every adjustment made a noticeable improvement. It’s hard to find someone you can truly trust with your car but after experiencing the quality of his work… I won’t be using another tuner. He absolutely nailed it and has earned a customer for life. If you’re looking for someone who knows what they’re doing and takes the time to get your car running right…I highly recommend him.

Great experience with Derek tuning my 2013 Cts-v. At first I was skeptical of remote tuning my v, but I do not regret it one bit! I never got to fully enjoy the car with the previous tune. After letting Derek work his magic, it feels like a different car. Great communication and very patient. I would highly recommend.

Derek did a great job tune in my 2015 Sierra. Wish I would’ve found him sooner, I would’ve saved me a lot of money not dealing with other garages that don’t know what they’re doing. but now it runs so good. It’s ready to put the Mustangs and Camaro down. Even with my crappy input to help with the truck, he explain things to me so he could get information out of me that he needed to get the truck running correct. Great person to deal with. I will definitely be back with my next project.

I couldn’t be happier with my experience working with Derrick on tuning my LS-based 408 stroker build. From the beginning, Derrick was extremely responsive and professional. His communication was outstanding, and he was often getting back to me with revised files and feedback faster than I expected—sometimes within minutes. No matter the time of day, he was always willing to answer questions, review logs, and explain what he was seeing. What impressed me most was that he didn’t just send a tune and call it good. He took the time to work through the combination step by step, reviewing datalogs, making adjustments, and refining both the engine and transmission calibration until everything worked together the way it should. Throughout the process, I felt like he genuinely cared about getting the truck dialed in correctly rather than rushing to the finish line. The end result is a truck that drives great, responds well, and performs exactly the way I wanted. It’s clear that Derrick knows these platforms inside and out, and his customer service is some of the best I’ve experienced in the automotive industry. If you’re looking for someone to tune your LS-based build, I would not hesitate to recommend Derrick. I’ll definitely be using him again for future projects.

Derek at DDTECH is hands down one of the best tuners I’ve worked with. I had other tuners try to dial in my twin turbo Corvette Z06 and fail, but Derek figured it out and got the car running right. What really stood out was how fast he worked. I would send him logs and feedback, and he would have revisions back to me within minutes. The man literally works like he’s available 24/7, and honestly, you won’t be able to keep up with him. My car is far from a simple setup, but Derek knew exactly what he was looking at and made the process smooth. He didn’t just tune the boosted areas and call it done. He cleaned up all the cruising and drivability issues too, the stuff other wannabe tuners try to tell you is “normal” on a modified car. It’s not normal. It just takes someone who actually knows what they’re doing. The car drives better, cruises smoother, pulls hard, and feels way more dialed in now. Dude is a tuning genius. If you have a boosted or heavily modified car, I highly recommend Derek and DDTECH. He’s the real deal.

I’ve always had a great experience with DDTech tuning. He tuned both of my cars and the entire process always went smoothly from start to finish. He is knowledgeable, professional, and took the time to make sure everything was dialed in correctly. Communication was excellent throughout the process, and he answered all of my questions clearly. I'm very happy with the results and would highly recommend DDTech to anyone looking for a quality tune. Thanks again for the excellent service!

Derek was very impressive in tuning my truck. Put new cam, springs, lifters, & pushrods in my 4.8L and drove it straight to Derek the next day. It ran horrible. When he got done with it, it was crazy how good it ran. He goes on multiple test drives with you and makes sure everything is operating like it should. It might have took 45 minutes. He is very good at what he does and knows his stuff.

10/10 Support and tuning. Derek has tuned my G8 with two different turbo kits and it is nothing short of perfect. Great blend of performance and driveability. You can tell he really cares about his customers with the quick turn around, great pricing, and quality tunes. Will not be using anyone else on any vehicle I own.
