Auto tune and pipe change
Forgive me if this is a dumb question. Currently I have true duals with a power commander 5 with auto tune. If I would change to a 2-1 pipe, would it just be a matter of plugging in and letting the auto tune work to tune to my existing target AFRs, or would the 2-1 have different preferences, if you will, for AFR?

I guess to clarify the question; I know the end result of the tuning will be different values as far as the actual fuel tables are concerned. But what I'm wondering is if the ideal AFR targets for auto tune would stay the same when changing pipes. For example, if my ideal AFR at 3000 rpm and 40%throttle is 13.6:1 based on my cams with true duals, would that still be the ideal target with a 2-1. When I initially got my map from Fuelmoto, the AFR targets were a bit on the rich side. I played around with the targets a little bit via trial and error based on some info I found on here. I have it dialed in pretty well now, and I'm wondering if I would be starting that process over with a pipe change.

Well, I would if I did actually end up buying a new pipe. At this point I'm just trying to figure out how much of that trial and error tweaking would need to be done, and if it be worth the trouble.
