Use the search function and you should find a ton of good discussion on it. Lots of people replace their stock IC pumps with a Johnson pump that seems to work better. I had a Renntech pump installed on my SL55 along with a additional heat exchanger to help keep the SC cool. I think there is even a DIY on IC pump install.
Good Luck

Whats the mileage in your car ? maybe need to change plugs ...
IC pump failure you wont really notice that much unless you are racing with someone then you see the different. Without the SC, the car should still running fast 349hp 391 torque.

If you had then you would relize the symptoms are exactly what he's describing. I had the OEM Bosch pump go bad and that's exactly the feeling of the car falling flat on it's face.

I haven't. Few members had the experience that they were not sure if it was the IC pump or not. So not always so easy to determinate the problem. Well, to be safe, just change it... about approx $200 with labor.

When the supercharger shuts down, performance falls completely flat. It's not like you'll get the performance of the W210 E55. Essentially, you have a normally aspirated low compression ratio motor that's breathing in really hot air whenever the supercharger shuts down due to the IC pump issue.
