I'm sorry, but there's no way a stage 1 bike is going to make those kind of numbers without some other work done, such as cams or head work.

I can see possibly 84 hp with the right 2-1 pipe, but not 103 tq. My stage 1 with SEPST and dyno tuned makes 74/88. I'm planning on doing a pro pipe this winter and re-dyno tuning it with hopes of achieving 80/95. If funds allow, I'm also going to do 204 cams at the same time, then we'll be talking 90+/100+

thanks for the info, 5% less equals ruffly 96tq and 79 hp. not sure it has 96 tq after reading other peoples dyno sheets. im going to have it re tuned. the bike runs great and is snappier, but at higher rpms like 4-5k it is not as quick as it was with the fuel moto map.
might be a week or so and i will re post the corrected dyno sheet. i am almost sure my inner primary bearing is going out as of the ride home today. lots of noise from the primary and other clunking when giving it gas. im assuming its the IPB from the rest of the post on these forums with the same issues.

Even at 5% high, those are still good numbers from just a Stage 1. I'd be happy with those just fine. But, if you don't feel that it's running correctly at higher RPM's then go ahead and get it retuned. I don't know where you had it done, but if at a Dealership I'd personally find an independant tuner in your area who has a good reputation. As far as I'm concerned, most Harley techs just don't have the knowhow or experience to be able to tune worth a shit. ANYBODY can own a dyno, but NOT EVERYBODY can tune worth a damn.
