I wonder if there was/is a calibration issue with the Wideband O2 that you were using on the dyno ???
Your HP/Torque numbers look fairly decent, and are not typical of a car that is running on the lean side.
Can you get a second opinion... different dyno location ???

Add to that the fact that does NOT look like the power curve of a detonating car (which he SHOULD be running any boost at 14:1) so something seems screwy. Also it seems very odd that he gets richer as RPMs rise... maybe raising static pressure and reducing the rise rate would be more appropriate.
Oh yeah and that pump probably isn't helping much running an FMU setup.

are you pretty certain that running a bit richer actually would yield more power on this setup? i assumed by the loss of torque at the top that when i increase fuel and drop the a/f by a point or so, i'll lose a bunch of power. it needs to be done, but i wasn't looking forward to that aspect of it.
there is another dyno in the area i could go to. it's just such a pain b/c they're all closed on weekends.
it was a pretty cold day, which might have had some effect. i don't know what other factors are relevant; i was running 94 octane gas because i'm still concerned about detonation. the car on the dyno after me, a fairly stock M3, was showing the sort of ratios i would've expected...
