So, I'm changing my exhaust from Samson Street Sweepers with no baffles, to a Speed Star 2-1 Header with a Supertrapp Muffler - Baffled.
Should I bump my ECU and make the mix richer, or leaner? I have a decent map on my PCIII. Do I need to start all over with the map? Anyone have any experience with this situation?
