2008 E92 M3  [0.00]
I have had 4 sessions on a dynapack (hub based dyno) and there are way too many smarts in the car to just test out of the box as the car knows its not moving and will refuse to allow manual changing beyond 2nd gear to get to your desired gear.

This is what we did..
1. Turn of DSC fully at the button as well as change your Msetting in the idrive to DSC off just in case
2. Trick the car to trip ABS, we did this by pulling a few runs in D5/6/7 and it just went off (alternatively pull one of the ABS sensors of the wheel)
3. At this point we were able to pull 3 runs and then the car convinces itself that you have been using launch control and will retard the engine. We saw 70hp losses on subsequent runs.
4. To avoid above just run the car on the dyno for 5 miles and it resets itself.

Here was my last run following AA software and dinan throttle bodies, not as good as we expected but transpires BMW didnt calibrate the TB's correctly and we had AFR problems.

Final thing is that the DCT seems to have a torque controller which we are seeing as a roller coaster curve, rather than the flatter curves that the 6mt guys seems to be getting.

will be dynoing again in 2 weeks now that the software and TBs have been recalibrated,
