I bought a Anderson Motorsports Pro-M Power pipe intake kit that came with its own MAF meter mounted on the intake cone. I have to send the MAF meter in to have it calibrated for my "applictaion." My question is what am i supposed to tell them i guess. My 95 GT has a full exhaust system on it, and bumped timing(these are the only mods that would affect the MAF calibration...) Do i have it calibrated for my stock injectors or should i put my 30lb injectors i have in the garage in and have it calibrated for those? The engine is stock, will 30lbs even make a difference? Will they hurt performance? I will be doing an upper intake soon too. I dont want to have to send it in for a stock motor, then send it back in for my intake 1 week later. Can anyone offer any advice?
