Just got mine back last night. 2003 RK with the 103ci upgrade, Samson slipon fishtails, S&S 570g..90 HP and 105ft/lbs at 4k rpms. I was kind of dissapointed with the HP numbers until i rode it. The tuner called me this morning and just said that bigger numbers could be had with a different exhaust, but im an old schooler and will not let loose of the fishtails. The vibration at idle from the stock download all but dissapeared, it starts way better, and you gotta hold on....also the longevity of the motor has increased, in my opinion, from not trying to acheive the big numbers....a way happy camper here.
