i mean i know your suppose to d/c your coil packs to prevent the car from starting. well it hurt if you prime the turbo when the manifold/turbo/downpipe etc is already on your block, or are you suppose to prime it when your stock header is still on your engine? 2 guys told me im suppose to prime it when my stock header is still in place but i didnt think it would matter since im d/c the coil packs so the car wont start.
