Remote tuned my HCI C6Z06 project. communicates well, responsive, got me setup with a base calibration for my first startup on the weekend. car is running great and drives excellent with the cam. Will be using DDtech for all my future tuning needs!

I highly recommend DDTech l, first time I’ve ever done a remote tune and didn’t know what to expect Derek made it super easy and will answer any questions you might have and walk you through everything, great to deal with and super happy with how my boosted Silverado turned out will be back in the future for any of my tuning needs thanks again Derek!

They did an amazing job fast response anytime I needed something edited. He emailed me back within 10 minutes, even if it was 8 o’clock, great guy and very affordable.

I can’t say enough great things about Derek @DDTECH. I’ve had multiple cars on multiple platforms tuned by others and nothing compares to Derek’s capabilities and customer service! By far DDTECH is the most knowledgeable, responsive, informative, and performance driven calibrator in the business. Don’t waste your time or money on anyone else when you can have the best with DDTECH.

Highly recommend using DD tech for any remote tuning needs. He got my GTO running awesome, super fast response time, great communication, will definitely be a repeat customer

Man I can’t say enough about this guy he has done multiple vehicles for me and I’ve been very happy with everything he’s tuned he’s very responsive and knows what he’s doing ! Do what he says and trust the process I wish I could keep him to myself but proud to have him in my corner when I need something done

Derek got me fixed up and was a pleasure to deal with. Super quick response time and top notch customer service.

No need to continue looking for another tuner, Derek is a legit 100% tuner, he knows what he is doing. I was reccomend to Derek after my previous tuner was getting no where for 3 months. Derek is quick to respond to your emails and his work speaks for it self. Any engine tuning work I'll need in the future, Derek is who I'm going to.

I was referred to Derek by a Facebook Corvette group member. I've reached out to him a couple of months before I actually got my vette put together. I'm new to Hp tuners and he was very patient and helpful, guided me where I needed help. He's very professional and Definitely knows his stuff.
My vette pulls like a freight train and is a pleasure to drive from idling, driving in a parking lot, cruising and all out beast mode and gets scary at times lol. The car is just plain Bad ass thanks to his expertise. He's definitely my go to for all tuning for all my vehicles

This man lives breathes and sleeps tuning cars. I promise it will be 100% running the best it’s ever runned after Derek gets ahold of it making more power with less timing I don’t get known of that stuff but I’m trying to learn as I still send him logs and best part about Derek is he gets right back to you within 10 minutes at the most. You just wouldn’t let anyone just work on your heart so don’t let just anyone tune your car reach out to Derek @ ddtech tuning.
