I recently put Rinehart 4 inch true duals, Arlen Ness Stage 1 Super Sucker, and after trying 3 different 'chips' I had the closest Harley dealer use the screaming eagle race tuner on my bike, but I am still having problems. at around 2500 rpms at a even throttle, I have a skipping/surging issue. The dealer told me that would be normal until they could get the bike on a dyno ($400 more) but that was the only way to fix it. I tried the RC extreme plug and go, I tried the Power Commander III, and now the Screaming Eagle. Any Suggestions?
