I have a PC3 on my 2007 street glide. I have not be able to locate a good tuner and or a close map which does all I want, mild performance, cooler running, and possibly better gas mileage. the bike is stock with a stage down load and SE slip ons. i would like an advance map to help with the rear cylinder temps. i was considering switching to the Cobra FI200 powerpro tuner? has anyone used this item and if so please describe both positive and negative issues. this way i can make an educated decision.
