I’m Michael “Happy” Gilmore, owner of Gulf Coast Tuning and Calibration.
I specialize in GM LS/LT tuning and have built this course around the same practical, repeatable processes I use when tuning real vehicles. My goal is to take the guesswork out of HP Tuners and help you understand not just what to change, but why you’re changing it.
No endless searching through forums or piecing together random videos—just straightforward Gen 3 tuning strategies you can actually use.
