Two Guys Garage - Hypertech = 120HP gain?????
They were tuning Sam's new GM 6L deisel truck with a Hypertech handheld tuner and they claim to have improved HP by 120 and tork by 85. This was on a dyno measuring RWHP.
Is this total crap or what?
At 540 footpounds I'm going to swap my Gen 3 gas turd for a Hypertech tuned GM 6L deseil!!!!
