Das Problem liegt an den hohen Ladedruck mit dem 54er Pulley, gerade in den USA tritt es häufiger auf da dort öfter die ganz kleinen Pulleys verbaut werden.
Ich hab im amerikanischen NAM Forum ein paar interessante Postings zum Problem mit der DSC/ASC Lampe gefunden:

"I have had a 19% pulley for a year now, I had it installed at the dealer and I love it.
What you get is added torque. All it does is move the boost down a couple of 100 RPM. I like it best when you take a turn and want the torque to pull you out of the turn. I almost never shift over 5500 RPM.
I am sure there are the "lurkers" here that will give you a hundred reasons why you should have their set-up and not someone elses.
If you get a two part pulley you can change it if you want. One negative, you will get the DSC light to come on and stay on if you get into it during the winter due to "an out of parameters" response from the computer. There are threads here about that. When you restart the car it goes away."

"the map sensor is set for only 18 lbs of boost max as my understanding of it.. if you go overthat due to wheel spin or of the such. it will give you the out of range code. And yes im one of the 19% guys.. which i did start at the 15% then moved up to the 19%. At the high boost area of the charge.. the Pulley will tend to slip using the 19% which causes the heat and failure of the belts. this is the main reason its really not suggested for extended use."

"Help! My car keeps dieing.
Spraying out wet black exhaust.
SES light and DSC light comes on.
OBD2 scanner shows P0108 which is Manifold Absolute Pressure/Barometric Pressure Circuit High Input.

Had it towed to the dealer (2) days ago and they changed out the MAP sensor and of all things the steering angle sensor.

This cleared out the fault code and SES & DSC light goes out.

The dealer put about 20 miles on it on a test drive.
I put about 25 miles driving home and it started again - sputtering, engine dies at stop lights and exhaust is spewing out a wet black exhaust like its running very rich and SES & DSC light stays on.

Man, what is going on? Vacuum leak?

Any help or suggestions are greatly appreciated."

check the wiring to the MAP sensor, if it's shorting or something, it will look like a sensor fault. I think the DSC may come on as it doesn't know how to control torque if needed, because it doesn't know what the engine is doing. When I scan my car with BiM COM, I get lots of steering angle sensor errors. I don't think it likes the CAN bus in the car too much, but I haven't thrown DSC errors because of it.
