I have a '13 1200 S Touring with a full Termi exhaust. I have downloaded the Tuneboy trim files but none of them seem to make it run right. I still get surging around 4k rpm and a lot of sputtering on decel. I have looked into having someone do a dyno tune but I can't find anyone who works with Tuneboy in my area. Does anyone have some trim files they might want to share that would work?
