My question is at idle what is the normal boost pressure, when looking at the indicator in the car. My wife has a 2008 Saturn Sky with turbo. At idle it reads 0 psi. I don't think that is normal. This car is my wife's and I don't drive it. If any one can help thank you. All I ask is go out to your car start it and scroll through to the boost pressure and read when at idle and then rev it up and see where it go's to. Thanks for any help Gator.
