i have a quick question for you all. i have never owned a turbo car before and my wrx has a greddy boost gauge fitted. can you tell me what the readings mean and what i should look for from it?

i know its probably a stupid question for you all but would help me.

cheers

its a quality brand and the numbers go up in accordance with boost power. say 15 psi , well that means the turbo is pushing 15 pounds per square inch of air pressure back into the inlet manifold . its called forced air induction.

this is how i see it anyway.....

waits to be shot !

i think your car should be around 11-12 psi boost at that age ..
