The results worry me in any case - power should be the same with th M button on or off if you're WOT, so I wonder if there is an error in the procedure?
No error in the procedure..
Dyno your car by a pro race shop with a highly qualified operator and see what results you achieve..
Had 5 runs.. 1 with "M" off.. then 4 with it on..last 2 runs where consistent..
First dyno was two weeks previous and the temps on that day where 26 Deg C against yesterday 20 C.
6 cars went on the dyno yesterday.. Some made power and some didnt..All within the expected range.
Dyno has been calibrated frequently as part of its ongoing maintenance.

I think there would really be no need for myself as I only have 1900miles on the clock and its 3 months old......
No need to replace gaskets..
