Hi to everyone, i try to tune a 2 g37 on the dyno and the timing maps don?t do any changes at all. Always give me the same log of timing and the car can?t increase HP. Hptuners write me that the main map is trimming adjusting map, but i move every single map and vvel maps, vvt and get nothing, fuel is perfect the car made 311hp on the dyno, we use a other program, the one every people use before and the car made 340hp. I think is one table missing or the computer have some protection tables that I can?t see. Is not talking bad about the program because the car run good but is a constructive criticism. Plus a 2step or race rom can be perfect to be more competitive software
