Worth a shot swapping out belt on the supercharger.
Literally takes 60 secs and can make a world of difference sometimes.
Just my 2 cents.
edit****intercooler pump rarely ever shows on STAR. It's become a little comical here (every loss is blamed on pump) but it is worth looking at as well.

3k? you sure?
the kompressor is actived around 1800 rpms or so.. very close to 2000 rpms.
by 3k. you have full torque....
does thing happen after being in traffic for a long time.. maybe its heat soak.. aka: high IAT temps .. bad IC pump
you will loose some power if the car is running in hot weather for a long time.. and you are running stock pump and intercooler.. that's just the price we pay for having a FI engine.

Does the car lose power completely or just seem weaker. I think the IC pump failure just shuts down the supercharger, but the car should still feel and operate like you're driving an E500 (at least). If it loses power completely and feels like it is bogging, then maybe something else more serious

mine was doing somthing simular... it was the IC pump as i suspected...
I thought all was good... it just happened again today? To me it felt as if the car was going into limp mode. The RPM's were not a factor.
