Get the tune. You have significantly altered how the air is flowing through your engine. If you work with the tuner that you plan to tune when the S/C is added they will likely work with you on the cost of the tuning updates.X pipe is in.. waiting for my evolve headers!!
Dinan cans, xpipe, stock cats, and evolve headers. the question is if i should tune it or not because the plan is going S/c in a year or so. I'll need to do all my maintenance first of course.
