Testimonials

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

I was referred to Derek from multiple other G8 and CTSV owners using the LSA supercharged platform. Over the time I owned the car and supercharged it and did continuous upgrades throughout the process Derek was there every step of the way. He was also quick with replies, revisions and knowledge. He’s not just a tuner, he has real world mechanical experience with the GM platforms. In my opinion and experience with other tuners, Derek is one of the best in business. You can trust him with your vehicle.

Peak Power, Safe, Reliable. Dudes always working, car rides like stock but full throttle will make you shit yourself. His hardwork shows in the results, Dereks a great dude super cool. Highly recommend.

Absolutely amazing tuner, very patient and knows what he’s doing. Answers emails very fast and just an all around great guy to work with. Will be using in the future and recommending him to anyone who asks!!

If your looking for a tuner you have found him. Our shop has used Derek on 4 cars now and every time he knocks it out of the park. AND he answers quickly. Finding a tuner that answers the phone and knows what he is doing is hard. Thank you Derek! more to come sir!

Got in touch to get my truck tuned and was very quick to respond, the tune was dialed in very quickly and drives a ton better! Very informative and was able to pinpoint a couple other issues that will be addressed asap as well!

I'd highly recommend and will be looking at future projects coming also!

I've worked with Derek a couple times now on remote tuning and will not work with anyone else. He is very professional, timely, and knowledgeable. Always a great experience!

Absolutely the best tuning experience you will ever have. Derek took my car from not running to drivable on a Friday night at well after 10pm. After a few driving logs the car is an animal. Revisions come back almost instantly. Had a few issues with the car and by just seeing the logs he pointed me in the right direction. DDTECH is the only option for remote tuning on LS engines.

Always top notch support, very responsive and helpful. Tuned my 2013 ctsv 427/kong2650 setup and thing is an absolute monster.

He remote tuned my turbo truck. Communication was very fast and answered any questions I had. Truck runs great .

I’ve been dealing with Derek for this past month getting my 04 LSA gto remote tuned. First this guys work and customer service is nothing short of excellent. I’ve delt with plenty of tuners and this by far the best experience I’ve had, car runs great, and he’ll answer any questions you have! Highly recommend for sure!

Derek Dunbar with ddtechtuning is an absolute pleasure to deal with! He has been on the remote tuning for my freshened up LQ4. Just did a little cam upgrade, some headers and a fully new gasketed motor. His response time is impeccable. The fine tuning from the first revision to the sixth revision was awesome to see and feel. Also sent me a separate tune for just regular 87 octane so I don't have to run 91 all the time.

Cannot recommend this guy enough! Still have a follow-up log to send him here in a few weeks to make sure everything is up to snuff but I'm sure that if there are any changes to be made they will be made in a very timely manner!

hands down wouldn’t go to anyone else , worked out all of my issues that i couldn’t get done with any other tuner healthiest and fastest the my car has ever been

Excellent communication and rapid response times. Tuned 2 5th gen ZL1’s for me the same week and both accomplished pb dragy times!

If I could give derek 10 stars I would. He is by far the most helpful, knowledgeable and friendly tuners I have ever used. He has done a few vehicles for me and is my go to guy! I cant thank him enough for being as great as he is! Its really hard these days to find someone who not only responds instantly to keep the shop moving but he also is beyond thorough. Every customers vehicle we have built and had Derek tune is beyond happy. He makes sure the driveability is perfect, cold starts are as smooth as factory and they drive flawless. Derek you sir are an asset to us here! We all appriciate you a ton! Thank you for being as great as you are!

Best experience, hands down! Tuning was a breeze, and Derek took the time to explain all the log info to me. It’s so good to know there are still honest and trustworthy tuners out there.

If you’re on the fence about using DDTech — just pull the trigger already! I only wish I had done it sooner.

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!

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.

I’ve worked with lots of tuners, and gotta say Derek is a true professional and REALLY knows what he’s doing. Wouldn’t hesitate to have him tune another car.

Was refered by a friend. Never done any remote tuning. With Derek's guidance I was able to get the tune dialed. I have also been able to help multiple friends get there car tuned as well. Worth all of the work to learn. Derek is the man can not say enough good things.

Had an awesome experience with DDTech. Derek’s communication is best of the best. I did a remote tune with him on my modified 2011 CTS-V. His approach was methodical. He explained every step, and was incredibly responsive over email. I was the limiting factor in how long the process took. In the end, I’m very happy with the car. We reached the goals I had set out at the beginning.

Ive never had someone take the time to make sure everything was spot on with the absolute best customer service. His response times are the absolute best. Highly recommend

Great guy got me tuned fast! If you need it done asap he’s the man with the master plan! I tell everyone to hit him up for tuning services

Derek is one of the few tuners who has great communication and stays on top of things. He does great work and the turn around time is phenomenal! I couldn’t be happier.

At first I was skeptical about my first venture with remote tuning but Derek was highly recommended by a friend of mine who also owns a very reputable shop. Right off the bat he was very responsive, eager to help, troubleshoot and work around within what I felt like almost any time schedule. His dedication to the craft left me dumbfounded as I've never had the communication that I have with any other shop for parts, or work, or anything vehicle related. He's definitely a rare top class individual with knowledge that goes beyond tuning and I can't thank him enough for his efforts. The best advice I can give is have a detailed list of what you have done and what exactly you're looking for and he can get you dialed right in.

Derek is the man! He doesn't have five stars for nothing. He did a remote tune for me on a simple 87 Cutlass Supreme Gen 3 LS swap. Be as descriptive as you can be on how the car performs and changes and he'll be able to get it dialed in perfectly. Go follow him on Facebook and check out the badass rides he does across the world.

I’ve had Derek remote tune my setup, Kong 2650, and he was very straight forward to deal with. He worked with your time and let you know beforehand if he had to do it without a certain time of the day. However, every time I sent a log the revision was back ASAP so made everything seamless. Great communicator and def knows how to calibrate correctly. Thanks Derek!!

Going on my 6th maybe 7th vehicle with DDTECH and I don’t plan on going anywhere else. Fastest response and great final product.
