Have been working with Derek and DDTECH Tuning for a fee years now, he tunes every car built at my shop and helps troubleshoot when needed, Best tuner in the nation, will definitely recommend. 💯💪🏽

DD Tech is the way to go. I am on my 3rd remote tune and nothing but a positive experience. Two tunes with my 05 CTSV and now with my 2009. All it takes is a quick search and to look on Facebook to know Derek is the real deal. Especially in the V world. The tuning process is very user friendly and he makes sure your good to go. I was brand new to HP Tuners and he helped me get very familiar. I advocate for anyone to get a remote tune. Your getting tuned for real driving conditions and your top end. Your becoming familiar with the very software thats running your car and your a quick email away to get a retune or assistance. No dyno needed. The best of both worlds. He makes himself available and gives you straight no bs feedback. Get your car mechanically sound and talk to the pro. Thanks!

Starting working with Derek about a week or two ago and it’s been nothing but exceptional service. He’s very quick with responses and will recommend different things to try to make your car even better. I’m fairly new to the platform but he was able to get the car dialed without issue and within reasonable time. Hopefully a dyno session soon to further feel in🤞🏼

The only LS/LT tuner i trust. Response time and customer service is fantastic. If you want tuning without the bs this is your guy!

One of the BEST in the world of tuning cars. Been using Derek for almost five years and he has never fallen short or let me down I think he is the bar in which everyone else measures theirselves with. He is a constant professional with the patience to compliment. Great experience.

By far the most knowledgeable and professional remote tuning experience I have had. Derek Dunbar and team provided an extremely quick turn around to address all of my concerns and exceed my expectations for the vehicle on a stock PCM.

Always seen great reviews and feedback for Derek at DDTECH and knew that’s who I wanted to have as my tuner for my mild 07 Escalade build. Hit him up to ask some questions before I knew which route I wanted to go with it and he helped me pick a cam and got me setup with Tyler at Mont Motorsports to get all the parts I needed. Once I finally got everything installed he was super helpful at helping me setup HPtuners, get the logs and uploading the files to the truck as I never used hptuners before. Derek always had super fast responses and answered all my dumb questions quickly and professionally. Super happy with the outcome with this build and the tunes he provided. Highly recommend him to anyone needing tuning done! Will stick with him on this and all my future projects!

You won’t go wrong with Derek. He knows what he’s doing and you won’t find someone better to deal with. He did a great job on mine, and I heard back from him almost immediately. He will make sure that you’re happy with your tune before he is done.

Been dealing with Derek since leaving my last tuner with previous tuning issues and I have nothing but a great experience, response times are perfect, communication is perfect and of course working the magic behind the keyboard is spot on. Very happy with switching over no complaints or regrets at all

Had Derek remote tune my V wagon. Couldn’t be more pleased with how it turned out. Great communication and quick turn around on revisions. Highly recommend letting him.
