I've got an 89 GT. Only mods are equal length headers, h-pipe, borla mufflers, cold air, and 3.73's. I plan on buying a throttle body, mass air, heads and intake. I know a boy in my town that put a set of heads but left the stock intake and it really didn't help. My question is: Can I put my new upper and lower intake on before and tell a difference? or should I buy the throttle body and mass air on first?
