I purchased and installed a Wiseco 883-1200 conversion kit with jugs, pistons, rings, gaskets and seals on my 2008 Sporty. Worked fine and bike runs much stronger but misses at low rpms. I took the now converted bike to the dealer for to adjust the ECU which they claim they did but no noticeable improvement. I called HD Tech support and was told the dealer needed to use the $24.95 Screamin Eagle Pro Super Tuner software CD along with their Ditial Technician laptop to remap the ECU. I went to another dealer and they said I also need to by a different $450 HD ECU module. Another person said better to buy a $250 Fuel Pack from Vance and Hines.

Does anyone know the real scoop on this issue?
