I'm new to the lightning mods. I have 2001 L with a 4# upper, autologic chip, jdm throttle body, magna flow exhaust, and a few body mods. I'm just not happy with it. I need to know what kind of cold air kit I should get and what mass air should I get. I want to change the chip to a Diablo sport tuner and maybe have the supercharger ported and polished for better air flow. Do I need to change plugs and wires? What about injectors? Thanx for the help. I'm trying to learn this stuff. I believe if I do all of that I'll be happy with it.:rollseyes :idea: :shrug:
