No more low end power either, in fact on one run the stock tune made more.

The only possibility that I'm hoping for is that the guy running the dyno who is a pretty well known import (not BMW) tuner mentioned the extreme whistle that my car has above 4000 rpm. I thought it was from my throttle spacer but he said it was definitely a whistle from an exhaust with a lot of restriction.

I'm hoping that my car is just bottlenecked right now and the tune is not able to be a factor.

Graphs to follow later tonight when I get home.
Hmm, can you post the graphs with overlays of all the runs (w/ and w/out tune?). Sounds as though shark may still be the better way to go, but until shark and this tune are dyno'd side by side consecutively, we will never really know.
