Re: problems with SRT-6 **Help**
I had this same problem and I live in Southern CA. It took the dealer two weeks to find out what was happening. It turned out to be the sensor the the supercharger. What happens is when the supercharger is about to overheat a sensor will kick off the boost which causes the affect. It would happen to me about 10 min after driving the car and wouldn't stop until I let it cool. It started doing this one night when I was driving home from the races and I had a long night of racing down the strip. If you are still having this problem take it to the dealer and tell them the supercharger protection cable is kicking on to early and makes the supercharger stop the boost. Its part of the boost control.
Hope this helps it was a b@#$ trying to explain to the dealer and trying to get it to do it for them but once I finally got it to do it in front of them they had to choice but to fix the issue. In fact when they run test there are no errors that show up in the ECU. its wierd.
