Should I be afraid of a SuperFlow dyno?

Hey guys, sorry this is taking so long. The guy sent me a crappy graph. I emailed him back and he is supposed to send me the actual run files so I can post the graphs and even do before after graphs.
I just don't want to say until I can post a graph.

Ok, so I still don't have the files. I starting to think they've lost them or something. I don't see what the big deal is.
So, I give up. The graph they did send me used standard correction with smoothing set to 5. So I'm using the same CF and smoothing for the before #'s.
BEFORE - 314.91 rwhp and 272.02 rwtq.
AFTER - 350.27 rwhp and 298.46 rwtq.
Gain is 35 rwhp about an 11% increase. 26 rwtq about a 10% increase.
Not too shabby I guess although still seems a bit low to me. I really think my peak tq (butt dyno estimate) is around 3000rpm so I think the tq number would be higher if the operator wasn't so daft.
I also still think I had one pull that was a tad higher but I could be wrong, it's all fuzzy.
So I was hoping to post a pretty graph with both the before and after #'s on it, but oh well I guess. Maybe I will eventually get the files and be able to do so. This really sucks because I even lost the one decent looking printout they gave me. I'd also like to see what the #'s are without smoothing and uncorrected.
Let me know what you guys think.

Headers AND exhaust. I'm also pretty sure that I put the smaller pulley on after the dyno the last time. The before #'s are at 7.5psi and the after are at 8.5 psi.
BTW, couple of things. I'd probably make 40-50 more hp if I could raise the rev limiter 1000rpm. The hp line shows little sign of stopping, going up all the way to redline. I'm fairly sure the operator didn't turn off overdrive, which he did last time, so the convertor was not locking.
Also, still makes LESS power without the intake / air filter on the supercharger. Made about 20hp less without it...

BTW, let me know how much you want for the auto once you get it out, I wouldn't mind having a spare to play with. Maybe find a few other mods to do.

Thanks Scott.
You know the funny thing is, I sitll think I make more boost on the street. The pulley is in theory good for 12psi (15psi with a 6.5 inch crank).
I know I'm losing a couple of psi through the intercooler. In fact, the car made more power without it despite the near 200 degree intake temps.
Hmmmm, what next.
