Interesting and thanks for the respect for the "other guys" too. Why do the red graphs fall shorter at higher RPMs?

in the dyno the rpm calibration is done at 3000 rpm. At 8000 rpm the diameter of whell change. Depending from tires, pressur... etc 200rpm is normal difference....
In ms I have 8200 hard limits histeresy 100. Log respect the limits.
The big difference of torque is for vvt. if not well driven, the bmw engine loss many hp

Seems like all the Tuner packages for newer BMW don't allow cam tuning.
That is crazy. On all cars I've tuned with variable cams, there are big gains to be made with optimum cam timing.
Nice work on the S54.
