How Do I Read My Boos Gage

[RHONE]

i have a lamco boost gage that comes from the dealer im not exactly sure how to read it can someone plesase help me it reads 0 at the center then .05, .1, .15, the other half is -.05, -.1

0 MPa = 0Psi
.09 MPa = 13.5 Psi (stock WRX max boost)
.1 MPa = 14.7Psi (stock STi max boost)


the negative numbers = Vaccum, no boost.

DOWNxSH1FT thanks again for the help after your info i tookmy car out for a drive and found out my boost was down it would hit 13.5 but instantly drop to around 12 then keep dropping and which was causing me to shift around 5000 rpm. after removing the blow off valve and plug i found that the plastic plug was breaking and falling into the tube after sucking the plastic out with a mini shop vac and praying to the turbo gods i put it all back together and now my car holds 13.5 longer and pulls strong right thru 6000rpm and i guessing none of the plastic got into the turbo. thanks again.

Glad i could help. Keep the BOV off your car. Unless you have a new turbo and major upgrades making a lot of HP the BOV will only hurt your car.

-safe motoring.
