Sorry if I'm posting this in the wrong spot, but I have a question about how to read my turbo boost gauge. I just bought a 2012 WRX and had the dealership install the boost gauge. I read online to expect about 14 PSI from the turbo. Typically the needle of the gauge hangs straight down (reference the image below) unless I give it some gas, then it starts to rotate clockwise.
If I push the car I can get the needle up to between the 0 and the 5, but no more than that. Should I be seeing the needle read up to 14 PSI, or am I misunderstanding something? All the values it hits on its way to zero, are those negative pressure values?
Sorry again for my ignorance, but I can't seem to figure it out. Thanks for any help you can give!
