Precision. Performance. Proven Results.
At DDTech Tuning, performance isn't just a goal—it’s a standard. Founded by Derek Dunbar, a seasoned GM technician and one of the leading names in remote LS/LT tuning, DDTech exists to bring the highest level of calibration and drivability to GM-powered vehicles across the country.
What sets us apart? Experience that matters. Derek began his career as a Mechanical Technician at Gerry Lane Cadillac in Louisiana, where he mastered the inner workings of GM powertrains from the ground up. Over the years, his passion for performance evolved into a full-fledged tuning business built on accuracy, reliability, and results you can feel behind the wheel.
Meet Derek Dunbar
With more than a decade in the automotive industry, Derek brings a technician’s precision and a tuner’s instinct to every vehicle he calibrates. He’s not here to load a canned file or guess his way through your build—he’s here to dial in your exact setup for maximum power, clean drivability, and long-term reliability.
Derek specializes in late-model GM platforms, particularly LS and LT engine families, offering advanced remote tuning services through industry-standard tools like HP Tuners. Whether you're cammed, boosted, flex-fuel, or just looking to get the most out of your bolt-ons, DDTech Tuning has the experience and tools to get it right the first time.
“The goal is always the same—give every customer a safe, responsive, and optimized tune that makes the car feel factory clean, even if it’s making 1,000+ horsepower.”
