Looking for some advice. 2004 Fatboy EFI, Stage 1 and 2, and V+H longshots. added by the original owner My question is, when i have the baffles out, i get some hiccuping, and sputtering, when driving in town or going down hill and when i start to accelerate again. I know the stage one is definetly done,and i was told stage 2, and not sure if it was ever mapped I really like the way it sounds without the baffles, i tried it with them in and had no problems. When i was explaing this to a freind, he told me i needed a fuel pack, or TFI, or power commander, to stop the sputtering. Any suggestions, also is it something i can do myself, and cost?
