I called V&H and the tech acted like it was the first time he heard of this problem and he spoke to his supervisor. Well the tech told me it was a Harley issue and I told him this issue occurred after I installed the FP3 and was messing with the autotune. He insisted it was a Harley issue and told me to have dealer check and fix the problem.
I pulled the main fuse and this did not fix the issue. Flashed it back to stock and removed but the P light still on.
Anyone remember or know how to reset this P light other than taking it back to the dealership. I hate that place.
Any help would be greatly appreciated.

Have been exploring options on how to fix the problem, and price drove me towards the Fuel Pak 3. I read most of the posts on the subject in H-D Forums, and figured that I would give it a shot. Man I am glad I did. Ordered the unit last week, installed the unit and flashed the ECM today with the recommended map, and solved most of my problems right out of the box. Besides completely solving the decel popping issue, I got a much better power curve as I ran through the gears, better acceleration, more low end power between 1900 and 2300 RPM, runs cooler, and much more responsive in general. Seems like it may be a touch fat between 2100 and 2500 RPM, but overall satisfied with how it solved my problem. Don't quite know when I will be ready to play with the auto tune feature, but I am sure it will happen at some point.

Some of the questions I saw in the forum seemed intuitive for someone who works on computers a bit. FP3 can see all of the sensors because it is plugged into the diagnostic port which feeds information just like it does when hooked up in the dyno booth. It uses the O2 sensors, Throttle position sensor, and temp sensors without having to hook to them directly. You see everything on your phone just like the ECM sees it. A lot of the other issues seem to be related to people using every little feature of their phone, and crosstalk is what is killing some of the results people are seeing. Turn off wi-fi, and just run bluetooth while working on the tuning process, and you should be good to go.

At any rate, I'm a happy camper with this one, and it saved me at least $500 over the other options like dyno tuning (ripoff) and other power management systems that cost a lot more than the $330 I paid for mine.
