Speaking of charts...
Steve...you of all people should know you can't get a 20% increase in peak HP at the rear wheel from a bolt-on exhaust and Power Commander. 12 to 14% is about all you can expect. FuelMoto claims to have tuned the bike from stock of 135 to 160+ peak. That's a whopping 25HP!
But one of his customers has already checked his numbers. He took the bike to an independent tuner and dyno'd the beast. He got 12% (16 hp)....not 25 hp. 16 is very respectable. 18 would have been surprising. 20 outlandish. But a 25 hp gain at the rear wheel ...on a C14...with nothing more than a full exhaust, a BMC, a PC5 and flyectomy? It's just not credible.
You can see Tom McCoy's (user: Anubis) graph for yourself here:

Come to think of it - you do actually get 30-35 HP gain at the very top, because the factory system drops off dramatically at 9900, not that you'd live there, but those gains are very real. It's unusable power, but it IS there in any case. That's the basis for Jamie and Brock's claims.
