I just installe a autometer boost/vac gauge to my 02 wrx and it should ony be boostig stock but it shows 17.5-19.5 I tapped the vacuum line into the by pass valve vacuum line. does anyone know how to fix this
why should it only boost 13.5 in 4th and 5th? I think it goes up way past 15 psi in fourth and fifth. I got the car from an 65 year old doctor who has owned it since it was brandnew. he had the car fax so I knew it was legit
from factory max boost is 13.5, they tuned for fuel consumption and all that stuff we hate. thats y max boost only come on in high gears, more load is possibly the reason, who knows.
so I just noticed when the car is offthe gauge is showing I'm at about 4-5 psi. is that normal? also my vaccum goes between 5-10 when I'm idling. any suggestions
