That said, I encourage you to go out to WSID on a Wednesday (or Sunday) and do some 3rd/4th gear logs. It will be of of at least equal use to you as a dyno plot, but is way more fun.
The ambient air temp today was only 23 Deg (albeit humidity is around 80%) but I think you're correct in that the butt dyno has become accustomed to the extra power gained from the fmic and DP's.
I would definately love to head out to WSID sometime, how often do you guys get out there?
