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+

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.

sae is the one that is most recognized for hp and tq about 5% lower than st or din methods because of a correction factor making it more real world .if your butt dyno is happy don't worry about it . if your looking for bar stool bragging rites then you need to consider head work cams and possibly bigger bore. just depends on what you want riding style etc. if you ride in the normal rpm range it looks like your fine if you rev high then the curve needs to be moved right .enjoy your ride most harleys don't put out much power I'll attach a sae dyno
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 ****. ANYBODY can own a dyno, but NOT EVERYBODY can tune worth a damn.
