Just got done having my Skunk dyno ed at Faibault HD in MN..
All stock with fullsac stage 1, new c pipe and 2.25 baffles!!

That's the happiest dyno I've seen yet.  Lets see the rest of the dyno sheet showing run conditions.

Happy dyno doesn't even come close to describing those numbers on a stock CVO110 with only an exhaust change and tune.  There is no exhaust system on the planet I'm aware of that will provide a 30% increase in torque, unless it's connected to a turbocharger.  Did this shop give you a before (totally stock) run for comparison?

The attachment is from Fullsac, and it shows what they claim for the Stage 1 package.  Even those numbers are probably a little optimistic, since they are STD, not the preferred SAE.

Nah it might be happy, but the happiest dyno in the land is Joe's in NY.  It's the one Hillside recommends.

Would love to see my bike on that Dyno

Is there supposed to be some sort of standard by which the made-up numbers are made-up?

Ya the dyno might be a little happy, but this is the new c pipe and the dyno guy said there running 6-7hp gain over the b pipe.. I didn't have a baseline because I did all the work myself, except for the happy tune.. I guess as long as im happy with the numbers and performace I could care less what the rest of your numbers are!!

It doesn't really matter what the numbers are on any given dyno on any given day when they're used the way they're supposed to be.  That is solely to make comparative runs to see if changes resulted in gains or losses.  The problematic fallacy comes from trying to say that "so much power" was "measured".  The only way you can tell for sure how much power is produced at the rear wheel would be to spin a lightweight drum with an electric motor (either DC or variable-frequency AC) and measure how much power (electrical) was required to hold any given speed against what the bike would accelerate it from if it could.  This would be extremely much better for tuning purposes as well because any drum speed (within target range) could be made and held at will while the bike's throttle was manipulated through various positions.  I imagine it'd be a fair bit more expensive than the stuff Dynojet is producing, though, and certainly more expensive to operate.  So we have to live with the fantasy printouts of Dynojet, et al...

Somewhere on-line there's a "reprint" of an article about them coming up with their dyno back in the day and they plainly say in it that their numbers were made up.

When comparing different dyno runs often with different dynos, it is just left over piece of paper after all changes are made during a tune. The Dyno Day is just a way to get u buying stuff/service...
Your numbers are what they are, if U like how the bike runs then U should be pleased. The rest of us are just feeling a little envy perhaps...

Really? I want to hear more about the C-pipe. Difference between it and the B-pipe.
Steve has not even chimed in on this new pipe he is offering as yet. Unless I missed it.

I don't think you missed it, as I haven't seen anything from him either. It's not on the Fullsac website.

I heard the difference is that the c pipe is a non-stepped header (the b is stepped). I'm not sure if it is a 1.75" or 2" pipe.

I would be interested to know only for the reason that I'm considering a Drago 2-1 pipe, and am deciding between his non-stepped and stepped versions, so I figure the performance differences between these 2 Fullsac pipes would shed some light on what works best for the 110.

I am not saying it is, but that drago pipe seems suspiciously like a copy of the rush pipe.  Might want to check that out as the Rush pipe and compare closely.  The rush pipe is a little less expensive too.   Who knows maybe rush is even the company producing it.

Rush does manufacture the Drago pipe...

That tune at the beginning of this thread is sporting nice numbers. It's a little sad to hear people talking it down...
I've watched bikes being tuned and had the pleasure of tuning my own bikes on Dynos over the years, and the whole point is to get the bike running optimally, period. 
13.2:1 AFR in the power band (from 2500 - 5300rpm) is ideal for most motors, and is what I focus on when I look at dyno runs.
That little band at the bottom that is cut off in the photo posted is the most important one in my opinion.

Like a few have said, if you're happy with how your bike runs, then your money was well spent.
