those charts don't tell you the AFR of the dyno runs, they only tell you what the AFR was set for in the TTS software.

if your VE (volumetric efficiency) is off (and 99% are), those numbers don't mean squat..
what was the AFR on the dyno on the runs?

I'm not sure that I received that data. Where would it be located?

Thanks, interesting. I just e-mailed the tuner requesting that.

Opinions on the loss of power? I'm thinking that it's the quiet baffles.

Suggestions on removing the browning?
Was the stock #'s from the same dyno that was used to do the tune?

I just talked for the 1st time last week to an Indy shop south of home and he told me that the dyno machine that he had would give usually around -15 #'s tq and Hp than others around here on stage 1 and cams job.
So again there is sometimes a big difference in dyno's machines and operators.

there are several products that claim to remove bluing from chrome, I'd just do a search on chrome cleaners

Yes, same dyno. I already knew around what numbers the bike would put out stock but, wanted my bike on that dyno machine to have a legit before and after comparison.

By removing the Sharktail tips and replacing the quiet baffles with the standard baffles, it gained 4.71hp and 7.21tq with the tune still set for the quiet baffles.

i think you should check into those $200 hooker pipes while they last. I wonder what the dual longs that come out on 1 side would look like with dual tail fins. kind of like a V ?
