Went and got the SHO dyno'ed tonight.

After talking with the guy, found out they have only had one other SHO in their so he was showing me his numbers vs mine. He wasn't sure who tunehe came in with but he had a tune and downpipes and nothing else, when he came in he was high 350's low 360's. After some adjusting with it a little and he left with just shy of consistently 400awhp. My mid range was a a decent bit higher but i think that was on the tune that he came in with.
One thing i was curious about is that he was asking me if their was anyway to keep it in 3rd when doing the pull from 1500 rpms. We tried S and D using the paddles but everytime you WOT it downshifts unless you're above 3500rpm, he asked because the owner of the previous SHO said he messed around with something in the shift patterns and his dyno run started at 1500 in 3rd gear and never downshifted.
I also asked why there were loops where its dropping torq/hp with those 10rpm increments. He said he could feel those surges while doing the pull and that he sees that even worse on the VW's.
Their was also a puff of black smoke out of the exhaust after each run when he lets off the throttle, im guessing its running rich but im not sure if thats normal or not. All in all its still not to bad.
