    I have a c15 acert, NXS, personality code 52, which is heavy haul 550 hp tune. My FLS is at -9, FTS at 8. Does anyone have some numbers that would work better then those? I dont have access to a dyno, however have heard of the 74, -19 numbers working well. Any input is apreciated as always.

    From my understanding, you do not want to play with those settings on an Acert. You will do more harm than good.

    FLS/FTS numbers are used to "fine tune" an engine as far as I know. I could be wrong.
