Exactly, this is what worries me most. It is so far out of line that it cannot be explained by production variance. Also, 91 octane is the highest out here. I saw an article of how octane and altitude interact but can't find it now. To really make me cry, here are the unadjusted results...



The dyno shop has done 50+ E9x M3 runs and showed me some of the other results under similar conditions. The other cars were around ~340whp.
