Ok, hear's the deal- I've got a Steeda T/A and some other mods such as full new exhaust and C&L MAF, K&N, alum D/S. Would I want to get a chip to tie it all together or is that redundant since I have a Steeda T/A (currently set at 15 deg adv)? I guess the real question is do you gain any by adding one when you already have the other?
