Customer Testimonials

First, Derek got back to my emails super speedy. Got me in for a tune as soon as possible, and got it right.
Any questions I asked, he answered, and took the time to explain things. My truck feels more enjoyable and smooth. Just plain SMOOTH. the shifts are quick with no jerks, the throttle response is instant, the truck is way happier and so am I.
Once finished, he made sure to ask if anything else needed changed or any shift points adjusted.. very professional and respectable!
I’ll recommend DDTech to anyone thinking about getting a tune
Derek was amazing tuning my G8 and walking me through all the steps needed. Answered all my questions and emails even on Sunday's. Great pricing and fast response!!! Thank you
I had my truck remotely tuned but Derek. The problem with tuners today its hard to find good trustworthy ones. He's the 3rd tuner ive had because the other 2 just never got the truck right and seemed like they didnt want to take the time to fix it. They were to worried about other things. Derek nailed the tune and restored some faith haha. We went back and forth for hours with data logs and tune files until the truck was perfect. He is a must use tune for sure and I will be telling everyone I know to use him.
DDTech Tuning did an excellent job on my tune. Communication was clear and professional the entire process, and the revisions were quick and dialed in. The car pulls strong, shifts smoothly, and feels extremely refined—exactly what I was looking for. Data logs were reviewed thoroughly, and you can tell Derek really knows what he’s doing. Couldn’t be happier with the results and would absolutely recommend DDTech Tuning to anyone looking for a quality, reliable tune.
I went to him off a recommendation and when I say did not disappointed I would recommend him 1000000x over I’m over excited w/ my results. The customer service he gave was on point ever question I asked he gave an answer.. He gave me a lot of knowledge and took the time out to actually help me understand some of the things I didn’t understand thank you so much

Derek at DDTech worked his tuning magic on my G8 build. Boosted and built trans. Car rips. But can drive down the road like it's totally stock. Couldn't recommend him more.
Derek got my supercharged LS2 TBSS dialed in and running at its peak performance. Great guy and is an expert at his profession.
Huge shoutout to Derek for getting my truck dialed in. It runs great and the power difference is crazy. Super cool guy, great communication, and he really takes care of his customers. Definitely recommend him if you need a solid tune!
