sweet thanks snoopy. im kinda a rookie with this stuff so, would you guys reccomend putting in a new ecu chip i guess? Just for referance, i have a cool air intake, dc headers/downpipe, greddyEVO2 exhaust and just put a new trans in. basicly im lookin for more stuff to do to the car without supercharging/turbo'n it. any ideas would be great... other thing i was wondering about was weather to leave the stock cat i have in or if i was losing power from having a stock cat between the aftermarket headers/downpipe/exhaust
