My buddy has an 05 Road Glide that was built to a 95. True duals (Rinehart), has the PC-V with auto tuner on it. Now some days he says it runs great, some days he says it's terrible (back fires, hesitates). He's not getting very good milage (35). Has anyone got any ideas for him? I told him to get rid of it and go to Rev Performance, but he can't afford it right now.
