D was testing a chip for acura in his TL that added some decent hp, but he said the car threw a cel one day, so no luck.

I was talking about an intake...you know the tube with a filter? the one that looks pretty and sounds mean? 1-2hp...if you want more? cut a out a cold air hole on the body (hood/fender) and let it breathe from there...and it gets that 1-2hp by providing a better air flow (more open air flow)...however...your engine/computer is designed to accustom to air per fuel ratio, so it will adjust.

Exhaust is easy 10-15hp.
