I have a 2022 FTR Rally and for the sake of not spending an arm and a leg im probably just going to get the S&S Slipon - I was still considering getting a tune, specifically thinking about getting a powervision 4 with a canned tune to just because the bike already runs like crap from the factory - Has anybody done the pv4 and a canned tune from fuelmoto? Have you noticed a significant difference in the way the bike rides?
