My expectations then begin to set with what my results are going to be based off the research. Meaning, if I do not hit x amount of HP and TQ then my bike is not up to par with the ones I based my set up on. It then starts to get a bit more confusing and discouraging when I see a few people with the same parts/set up get varied numbers and at times it varies quite a bit. This becomes a struggle when you know you have the same set up as someone else but they got more out of their build then you did. Of course tuner, dyno etc all play a factor but my point is that this can take away from how the bike actually performs because if the performance exceeds your expectations and performs way better than before, then that is all that matters, at least in my opinion and experience...
I live between two dealers. The one I use mostly is about 15 minutes from me. I was visiting the other dealership about 30 minutes from me and the tech/tuner asked what numbers I had with my Stage 2 SE Torque Cam, Power Vision, Street Cannons, decatted header and I told him 90 HP / 109 Torque. He laughed and ran outside to grab a lady who was taking off on her RG and said "give me that dyno sheet" and proceeded to show me her numbers. She was well up in the 117 torque range with the same Cam/Tuner, but different headers/slip ons. I believe her HP was around 95 or more.

He then begged to tune my bike because he could get me much more torque than I have. All he talked about was this 'peak' torque he could give me and he never mentioned anything about the curve, rideability, etc. I looked him dead in his face and said NO THANKS. The tech/tuner I used told me before he did any work that he takes a conservative approach and his dyno does not give these super inflated numbers. All he talked about was rideability and how I would be happy. All of that to say ------------I'm extremely happy with how this things pulls like a beast even if my numbers appear lower than others. So I'm with you............as long as the bike rides great and exceeds my expectations, all is well

See post 9 of this thread although I see it is not a Harley torque cam but might give you an idea.

2017 FLHR - Bassani 2-1-2 Header; SE 447 Torque Cam; SE Heavy Breather; 4” Rinehart Mufflers.

Base line is dealer Stage 2 dyno tune. Final tune is professional Dyno tune (Fred@ProCycleDyno), using the old SE Super Tuner Pro.

New tune is perfect for my riding style.

not exactly what you're asking but think it comes close since I didn't do a stock run, but you can visualize it being slightly lower than the RED which is the SE Stage 1 with just the SEPST ECM Calibration (which I don't think would come close to their "up to 10% power increase" claim). Then the BLUE shows what the improvements are by dyno tuning the Stage 1 with SEPST. So the SEPST does have some capabilities that may be worthwhile to some to use it to its full potential after spending $300 on it and not just be satisfied with the loaded calibration which doesn't improve things all that much. Folks can decide if paying the $$ for a dyno tune is worth the additional gains, which was for me since it runs much better than stock.

That's a 107 with RS468 cam, stock decatted header, stock muffler cans with Fullsac 2" cores, Arlen Ness Big Sucker air cleaner.

Coming soon! 117 ci., ?cam, Fullsac X pipe. Big difference, we'll see.

Nice so what cam you thinking when you do your 117?

My plan is to start with the S&S 475 as I currently have one. I am trying to coordinate with Steve so we can do cam testing almost fas soon or as soon as I get the bike together, so it may still be a while. I don't think we will test the RS468 that is in the bike now. I haven't been impressed with what I have seen of that cam in bigger motors with higher compression. I have hi-lift springs on the heads so we can test some higher lift cams. I'm positive we'll do the TTS200 & maybe 250. I also want to do the TTS150. I might try to get a WM8-408, it seems to be a popular cam, the new Andrews 550 looks interesting, maybe something from Cycle Rama. I know Steve might have a few he wants to do from other suppliers. It is really hard work to do this and each cam takes 3-4 hours, so that will also limit what we test. If we do three days like the last time we're looking at 7-8 cams. Since the ss475 will already be installed that will save us having to install the first cam, but if we have to break the motor in on the dyno it will take some time also. If I can get a tune to start with I will do a street break in to save that time.
