Nope, however i had put e85 in the car that morning and drove normally to GIAC. No WOT or anything. The ECU could have been adapting to the slight fueling change. There are a whole host of things that could have contributed; too many variables to consider. O well, haha. 377whp 335i keeping up with GTRs and GT3s around a track has a nice ring to it.
