Got it done.
Superflow Windyn Dyno - STP corrected. SR Racing - Lexington, KY.
4 pulls. 3 in second. 1st two pulls heat soaked and second gear to 6000. 445 rwhp @ 5700 rpm 455 lb/ft torque @ 4300 rpm. 11.5 - 11.8 AFR.
3rd pull in 2nd, 4th pull in 3rd after cooling down for couple hours. 446 rwhp / 459 lb/ft. Pretty much identical #'s 2nd and third, hot or cooled. My AFR gauge showed 3rd gear pull at 10.6 AFR. They didn't put in the sniffer on the second set of pulls.
Can't say I'm happy about the numbers. Definitely expected higher torque numbers. There was a trophy awarded for highest HP. Got beat out by a late model Ram Cummins Diesel twin turbo. He put down 449 / 8??

Was pretty warm. 90 degrees.
I'm not really to worried about the number. I just do not understand why there would be pretty much no difference between a locked or unlocked pull. No difference between a pull with a 40 degree difference down in IAT's and the big one, only 1 hp difference in a pull with 5 degrees more spark advance. I think that should make a considerable change in the numbers?
Am I wrong?

I know mine was slipping through the stock converter and im hardly making the upside of 280rwhp.

Hmmmmm...IMO, your hp numbers look in the ballpark, maybe just a tad low, but the torque is awful low, too. Did you try the meth? You added 5* overall, and no change? That's wierd. But sounds like a decent day, overall.
