Just wanted to give my impression of the vance and hines fuelpak fp3. I have a 2014 fatboy lo with short shots and SE stage 1 air cleaner and had the harley download (waste of money) done. The bike was sluggish, alot of deceleration popping. I used the fuelpak fp3 and wow I'm impressed. It took care of all the popping, runs cooler, and great throttle response. The fp3 also has the auto tune I'm going to run at some point. So if anyone has been tempted on trying the fp3 it might be a good option.
