Hopefully auto-tune works. American Custom Mufflers suggested a map that allows for a really free flowing muffler when set up for the "Deep Rumble" baffle and a stage 1 air cleaner.
I have 2018 Fatbob 114 and replaced the exhaust with a TBR 2 into 1 exhaust. I bought the FP3 for it but for now they only have the Vance and Hines Shortshot maps for it. So i used that map and performed an autotune with the FP3 for about 1.5 tank of gas. Then I sent my map to tech support for them to evaluate the autotune. They tweaked my tune and sent me the map that was cleaned up. I’ll let you know if it works for me. AS far as I can tell, they are telling me that autotune gets it super close to what you need.
