at 6000RPM and is still climbing but I shift there.
True, I tasked them specifically for this, and the
big clutch, etc. How spy's piece compares, can't
say. But we are not that far apart on the stall/STR
specs (3400/2.1 vs my 3500/2.0).

I just look at so many graphs on a daily bassis i can see when something doesn't work right.
