I have recently installed a stage 1 on a 2007 Sportster Nightster. The kit consist of SE Air Kit, Vance & Hines Short Shot Staggered Exhaust and Fuel Pak. Since doing this the bike sets this code. I have driven about 100 miles when finished the bike seemed to have a miss in the rear cylinder. The bike also, seems to hesitate intermittently. V & H tech keeps telling me to relearn mode 19. I have several times, more like 8 times. Still hesitates but since clearing the code I haven't experienced a miss in the rear cylinder and the code has never returned as of yet. At one point, the bike would not even drive at low speed. I'm wondering if anybody knows how to manually program the stepper motor module or what module I may be able to program totry tocure this problem.

Thanks!
