i've pretty much decided that im not gonna run a fmu (have heard bad things), anyways i have a t3 turbo kit im installing on a dohc zc with a pm7 ecu. the car is a 89 hb with obd0. i was looking at a greddy e-manage but dont know much about them. would it be better to swap out the pm7 for a chipped si? i live in the middle of nowheres (that means no tuner shops for probably 350+ miles). which would be the easist for a beginner to tune with?
