Anyone with OEM tune care to share what their normal operating range for Manifold Air Pressure (MAP) is? I know at sea level with the engine off it is about 14.7 PSI. With the engine on at idle I'm in the range of 5 PSI (10 PSI of vacuum) and its goes up well past 20 PSI as I redline because I'm boosted. I have an aftermarket 4-bar MAP sensor so I just wanted to see what a stock MAP reads like. Not sure if I need to recalibrate anything.
