Running rich up top? (dyno included)

Hey Everyone,
I went over to New England Dyno (http://nedyno.com) to get a few baseline runs in before I apply the Evolve tune which I'm still waiting to get back from Sal. Everything went great and other than the brake and ABS lights coming on the dash, there was no problem running up to redline for the dyno runs (no dyno mode needed or fuses to pull).
The one thing we were surprised to see is that on all the runs the car starts dumping fuel in at high RPMs and really running rich. Anyone have any idea why this might happen? As the car got hotter it seemed to dump even earlier in the rpm range so we're thinking it could be heat related?

TIA!
