Hello all.
I recently purchased a modified 86 GN with a stroker kit, champion iron heads, champion intake, 6766 precision turbo, Champion fuel rails, full fuel system (680lph racetronix duel pumps, Teflon fuel line kit Lucas low impedance 160lb injectors) The car currently has Eric's SD2 chip and a powerlogger. It has a 4" maf pipe and no mass air. Because of my lack of tuning ability and the desire not to hurt this motor I have made the decision to go back to a mass air set up. I need help with the correct size maf pipe and mass air to purchase. I will then call Eric and order the following (120lb injectors, maf translator and his 5.7 chip ) Can I use my 4" maf pipe that I already have and step it down to a 3.5 LS1 mass air meter? Does it matter what LS1 mass air meter to purchase? I have an old Tinman cold air intake that I can hook up. If the Tinman is a 3" would I be hurting myself by installing it or should I just hook up a filter in the engine compartment after the mass air? Your help would be greatly appreciated.
