you want to know why tuning the VE is less effective? the VE airflow table stops at 140 map kpa, and if you don't know already, that is about 6 lbs of boost. so you better keep it under 6 lbs of boost. another reason VE tuning is less effective is that it uses data from O2 sensors, which are unreliable outside the 14.7 afr range, so how do you even know what afr you run if you don't have a wideband.
the thing about fighting a retard is that even if you win, what have you won, and who are you going to brag to?
