Something of interest to all the AMG drivers, I tried this today and it does work.
As you know our cars have the annoying habit of 'learning' your driving habits and changing the shift patterns and throttle responses to match. So lots of constant speed/commute driving really seems to make them 'sluggish'. For Keyless cars just remove the 'stud' and use the key for this as it's not very good at turning 'off' with the key in :D
Do this:
1. Turn the ignition key to the on (not start) position.
2. Press the accelerator pedal to the floor and hold for five seconds.
3. Turn the key to the "off" position (don't remove the key), then release the accelerator pedal.
4. Wait at least two minutes for ECU to reset.
This only resets the 'learning' transmission to default mode, nothing else. No damage can be caused etc. And if you end up getting stuck in traffic etc again it'll relearn over 40 gear shifts
