I bought an 07 Street Bob for my wife last year. 8,000 on the clock. It had staight pipes and a Hyper charger. It popped on decel and would not run without the engine light coming on. I have made the follwing changes: Python 2-1 exxhaust for more back pressure, performance and better sound. Heavy Breather to clear her leg on the mid controls. Power Commander 3 USB uploaded map for Heavy Breather and D&D Fat Cat 2-1. No more popping on decel and runs great. However. Engine Light On all the time. Trouble code shows P0108 P0108 Map Sensor Failed High Carb P0108 Map Sensor High EFI Any thoughts, suggestions, explainations would be appreciated.
