This thing is a blast! GM would have doubled there sales if they would have done this!!! Anyone who has owned a diesel Duramax with a chip would know what I am talking about. I get way better gas milage than I did with that slow 6.0. I have done Transmission and alot of motor upgrades to make this H2 pull away from a stock 98 corvette! It blows minds everywhere! Let us build your H2 Duramax or Escalade (any 03-up gm truck).
