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!

I hired Derek to tune my texasspeed crate engine I put in my C6 vette because I had many bad experiences with tuners in the past. Not here, he’s the best for a reason. Extremely patient, honest, constructive and he knows how these cars work. Day or night you have a problem he’s got your back. Would recommend to anyone who wants their car to win races and drive home every single time. 10/10.

I've used a hand full of tuners over the last couple of years and I gotta hand it to Derek, he's the only one I'm going to go back to. Only tuner I've ever been satisfied with. Awesome tuner, zero complaints, nothing but good experiences every time. You'll always have my business that's for sure!

Great customer service. Precuse and informative about what’s being done and what would be best. Will certainly be coming back and recommending.

I had an excellent experience with DDTECH TUNING and owner Derek Dunbar. Despite the time zone difference being in Morocco, Derek was incredibly helpful, professional, and patient throughout the entire process. He worked diligently to ensure everything was done perfectly, even when I faced some obstacles with my car. His feedback and customer service are truly top-notch some of the best I've ever received. Thanks to his expertise, my CSV CR8 runs great, and I couldn’t be more grateful. Derek helped me accomplish a childhood dream with a car I’ve owned for nearly half my life. I will definitely be returning for futur tuning and will highly recommend him to all my friends and family. Thank you Derek!

Hands down one of the best tuners I've worked with. Derek remote tuned my car. Had me gapping people and had my car dialed in for a race weekend. He was extremely quick at responding back. I didn't need to wait days or hours for a response back like some other "well known" tuners. If you have a LSA this is your guy.

Swapped a cammed/ turbo’d ls3 and built 6l90 into my RCSB, we had a few hiccups to deal with we figured out when we started the tune but Derek was patient with me fixing it and now the truck runs and drives awesome!

awesome experience getting my truck tuned! Super easy to work with, quick turnaround, and the results speak for themselves. Truck runs amazing — definitely recommend him to anyone needing a tune!

Give Derek@DDTech a call.

Top Tier Tuner. Couldn’t be happier with the end results of my car. Got all the hiccups resolved that other tuners couldn’t figure out. Communication is out of this world, quick responses no matter the time. DDTECHFTW
