    Think you meant 1.5 bar here...

    Technically, the stocker is a 2.5 bar, meaning -14.7 to 22.5. However, the stock ECU is only programmed to about 10 psi boost, so it goes blind to any signal above 10 psi or so. Aftermarket ECU's could possibly be programmed to handle higher boost levels, but that doesn't necessarily mean they are.

    I have no idea. All I know is that the stocker doesn't respond to anything over 10 psi regardless of MAP sensor reading.
