Stock GTR Map Sensor reads up to 24 PSI.

The issue isn't that the sensor can't read it, if you go into actual values the MAP sensor can read the boost just fine. I know this for a fact because I have personally done it on my car since I don't run a boost gauge on my SC setup.

The issue is that the car is NA from the factory, the computer is programmed to think any positive pressure is the sensor reading something incorrectly, hence the fault.
