I have had a BSR Stage 1 or 2 ECU on my '99 lpt for several years. It's uncertain to me what really constitutes the difference since BSR's site shows both having the same hp/torque. Some say stage 2 is a new cat-back, and others (BSR's U.K. web site) shows it being the ECU plus a a high flow air filter.
Well, the car has a K&N filter. Did that make it a stage 2?
Last week I installed a 3" down pipe with high flow cat (Magna-flow) and a 2 1/2" cat-back exhaust with Magna-flow center and rear mufflers.
Does that mean I now have a Stage 3 tune? Or would I need to update my ECU to take advantage of the new exhaust?
