I, as stated before, have over the years had a Power Commander with professional tune on a Road King Classic, a Race tuner with Professional Tune on a SEEG, a TTS with the free Fulsac download first then a professional tune using the TTS on the same SERG and now a FP3 with a set of 1.75" Fulsac baffles on my RGCVO.
Those of you who are bad mouthing the FP3 do not have one. I bought it for $289 from Eastern during a sale. My bike runs great, gets 45 mpg, has no decel pop, has a 6000 rpm redline, runs cool, runs cool, did I say it runs very cool? is VERY smooth thru-out the RPM range, has the throttle to throttle body ratio increased by approx 25% and cost $289 Complete, flashed, done done done. No need for anything else.
Please do not tell me it would be better with a professional tune, it would not be better, FOR ME, because I am fully satisfied and I do not have to have anyone beat the hell out of my bike for hours making a sometimes somewhat educated guess' until they get to a point that makes the bike happy.
Those days are over for me, maybe not for you. But you should not bad-mouth the auto-tune feature of a FP3 unless you have completed it and ridden the bike. You may have a few more ponies than me but I no longer care. Mine does everything I want it to do.
