I just replaced the bad stepper motors in my 04 supercharged. It's been over a year in the making. Also fixed a burnt out bulb for the passenger thermostat. Wasn't too bad a job. Have to be very careful with the thin leads on the motors. Also, don't forget to plug you driver info screen thingy connector .

I can't get my boost and my temp gauge in the right spot. I also think my rpm is reading a little high.

What position should the boost needle be at ignition off, ignition on, idle, and crusing then letting off throttle? I remember it reading about 6psi at full boost. But I can't remember if it went to -10psi when letting off throttle on lets say normal highway driving.

The temp gauge I believe should read about 2 ticks left of high noon on the gauge when at normal driving temp.

The rpm's I believe should be at about 600rpm at idle when at operating temp and around 1750rpm when doing 65mph.
