Does anyone positively know what MAP sensor is from the factory. I am working with an STS Turbocharger system & was setting up my basemap to get started with, however I do not know which scaler setting to use & I am not sure if GM even put a 2-3 bar sensor on these cars. Any help would be good as this is my first efiLive install, & I want to make sure all is well before initial startup.sdf
