i have dragos TD with 4" setup,Ness Stage 1 AC and SERT. Had a harley mechanic tune bike for me with his laptop no dyno. He did a good job, he plugged in what i had and uploaded the map. The bike is 90% there without a dyno it will never be 100%. decel pop is slight but bearable. in summer the bike runs crappy but i understand that is always the case. I dont think u need to change tuner just give it to someone who can tune with it. In NY, Maroney's in Newburgh has a great tuner. Good Luck
