Took Big Bad in to INTENSE today to get the PCM looked at...I think Brian managed to nail down the torque management issue that was holding me back. That and it'* definitely running that high-stall converter a lot smoother.
Best of all, ZERO KR during the scanning run, once the TM was turned down.
Got myself an Interceptor gauge, too. I'll be keeping an eye on KR for awhile, and if it stays at zero, I'm moving down to a 3.2"...
