Does the Power-Button give more power?
Time and time again I've heard it just sharpens the throttle response and doesn't really give more power, I refuse to agree with this statement.
I swear it gives more power;
I went up against my friends stock E60 M5 with Power off and was lagging a foot behind him.
With Power in the Sport+ setting I could easily pass him!
Runs were done consecutively from 0-100 at the same day at the same place.
would a aftermarket tune change this theory of the Power button not outputting more hp & tq
