I have a new 2008 FLSTC Shrine Heritage Softail. I had the dealer install Rush 2" Slip-Ons, Screaming Eagle air cleaner and a Dobeck TFI. The bike runs nice! I have no popping on decel and the bike sounds nice on idle and when crusing. However, I have noticed that the bike sounds a little too loud when I need to give it that extra throttle like up hills and accelerating. So I'm considering a baffle change. I know that the Rush products make it easy to change baffle sizes with just 1 screw. My question is, if I switch to a more restrictive baffle (from 2" to 1.75") do you think that I will have to adjust my TFI? If so, which POT(s) would need to be adjusted?
