Put thunder headers on the 15 road glide, Hooked up the FP3 and all is well so far, gona burn some gas today and head to Washington and see how it performs. One of the biggest improvements was that I am able to adjust the throttle and how it controls the bike. It was pretty jerky every time I hit a bump and would shut the the injectors down causing a slapping sound from the primary. Many miles of that bullshit cant be good on the drive train !! Think she's getting dialed in now. I like watching the real time info also, The bike so far squeezed out 76 HP and 86.4 pounds of Torque, according to the FP3. pretty cool stuff !
