Hay guys I have also had problems with the cpu saying the map sensor is bad. I took my car to the dealership after the first time at the light came on, they said it was the map sensor. They replaced it with another sensor and sent me on my way. A couple of days later the light was back, so I just reset the CPU by removing the neg. batt. cable and the light was gone, But about every couple of hundred mile it comes back. After cycling the key on/off 3 times i now get a P1188 code, I guess that means overboost, but when the light came on I was boosting like 5 PSI. I will be removing the MBC and Upgraded Pressure Pipe w/ BOV and taking it to the dealer. I will keep you all informed of the problems.
