"The way most ECU overboost protection works is by monitoring manifold pressure through a pressure sensor. When the readings go too high, the ECU stops pulsing the fuel injectors. On the Legacy Turbo, this happens when the ECU reads a pressure above approximately 28 psia for longer than approximately 3 seconds."

 

 

since we dont have a factory MAP sensor, we'd be better off going with MS, right?
