ECU/TCU reset
I have used the ECU/TCU reset procedure on both my old AMG's (C36 and C32) with noticeable results in each. Most MB dealers do this when they service the car because it will be more responsive and snappy to the owners. I tend to poke around a lot in the SLK with it in C-mode and noticed that when I switch to S-mode it went back to being more responsive. I suspect that it learns in each mode independently. The throttle response will be better and the upshifts snappier.
