Another thing 'PencilGeek' mentioned in his dyno articles was airflow. If the S65 does not get proper airflow through fans, it cuts back power a lot.

My guess seeing other similarly modded M3s to be around 380 - 390 wheel hp.
Good points.
The numbers surprised me.
I am going to try again at another shop.
Does anyone know anyone else that has a dyno in Calgary?
