436RWHP, 479RWTQ.. HP stayed above 400rwhp from 4.6K-6.6K RPM and never dropped below 475rwhp throughout the whole run starting at 4.4k RPM.
It was not peaky so peak HP kinda sucked but it was flatter than snot and would have been pretty damned fast compare to a centrifugal with the same peak power. I just wish we could have started the run earlier in the powerband to see what the TQ could have been. We we having trouble keeping it from downshifting on the dyno so we started the run after 4,000RPM. Not bad for a first tune with a turbo and meth. I can only imagine what we would have gotten out of it with what Rick knows now.
Ohh, meth only at those kinds of boost levels will suck up QUITE a bit so expect to check the meth tank weekly if not more. On one night I went through half a tank!

Glad you're lovin it though. The TQ must feel awesome in a dialy driver.
