hp and tq opinions please

2012 fxdb with bassani road rage 2 short, stage 1 air cleaner, pc-v. had a fuel moto map which worked great. just had it finally tuned after 21,000 miles. the fuel moto map was fine i thought, but just decided to finally get it tuned. after the dyno tune i got 3 more HP compared to the fuel moto map. which is not much. so basically fuel moto does a great job. i ran there map for over 21,000 with no issues. but the bike does run better now and is a bit quicker. i spoke with a man on a ride today who has the same bike with a thunder header, PC-v, stage 1 A/C and SE 211 CAMS. his numbers are 99 HP and 99TQ. I thought his TQ is kind of low for having cams. his bike was dynod by the dealer though. im sure that has a lot to do with it.

the new numbers on mine are 103 torque and 83.7 hp.

what do you guys think of these numbers it runs great, just curious to see what others think.
thanks

I think the numbers are respectable.

I just had Rineharts XT True Duals installed on my CVO S/E Ultra (110 stock) and it dynoed at a little over 90HP and 110 ft lbs Torque.
These aren't racing bike and you can buy many bikes right off the showroom floor with a lot more HP & Torque if that's what you're looking for.

They seem right in the ballpark for $$'s invested in the engine. I added a soup to nuts 97" street BB kit and from my piped/PC III'd 88" to the full blown custom tuned 97" kit was NIGHT AND DAY DIFFERENCE ! I'm at 96 hp and 103 ft/lb and after my custom tune, my engine runs SO perfect weather it's 85F or 45F ! I get even better fuel economy with the 97" vs when it was a 88" (I have custom street velocity ported heads also ) .

Sorry, but your numbers are hard for me to believe with just a Stage 1 and dyno. Feel like posting your sheet?

Numbers seam way high for a stage 1 96". Typically upper 70's for hp and mid 80's tq. The guy with the 211 cams is even a little high without headwork.

here is the sheet, maybe i have read it wrong. but i think it is simple to read please correct me if i am wrong.
thanks

What method was used to dyno your bike, STD or SAE? I don't believe the dyno sheet shows. If STD was used, that could explain the high numbers.

looks like the sheet says standard method not sae that explains higher #'s

What is the sae method. Think I can get a copy of it from the guy that tuned it. Or is it a different type of dyno machine. when it comes to wiring up bars, swapping fork springs and oil, exhaust and intake mods I have no problems doing any of that. I do it all at home, it's simple. But I have no clue about dyno charts. But IM wanting to learn about the methods used

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
