About
Kenny Sampson is the tuner behind TurboGixxer Tuning. From the grassroots era of high-boost four-cylinder Hondas and Acuras to modern Ford and GM V8 platforms, he brings a methodical, data-first approach to every build. He calibrates factory ECUs and standalone systems, including MoTeC and Haltech, for street, drag, and road-course applications. He prioritizes drivability, repeatable performance, and engine longevity over chasing a single peak-horsepower "hero pull."
