boost

  1. General Maintenance, Troubleshooting & Accidents.
    This is driving me nuts. I usually shift at 3k driving around the city with about 20% throttle and never fully get out of vacuum. Is this the case with everyone? Looking at my logs the closest I get is -0.9. Seems like I should be at least seeing 0 no?

    When I start my car and start driving immediately my car will boost 9-11 psi for only the first two or three gears, after it won’t go past 4-5 psi at all after that unless I turn my car off then back on. Has anyone had this issue?

    Hello all. First post here. You guys are my last hope so hopefully someone can point me in the right direction. About 2 months ago, I installed a new stage 3 clutch and 9lb aluminum billet flywheel on my 05 WRX. The car ran fine after this but my desire to continue upgrading it was...

    Hey guys, just read the Gauges FAQ and I was wondering if I could get your advice. Was looking at the SMY Clustermaker gauge pod and I think I'll be getting that, and I know a Boost gauge is a must, but in your opinions what other gauge is most important to have, for say a daily driver with a...

    Problem: My factory installed boost gauge won't light up. I bought my '02 WRX wagon last April that came with the factory installed Lamco boost gauge on the column but the light has never worked. I just figured it didn't come with a bulb but recently took it apart and sure enough it does. I...

    Stage 2 w/ Cobb AP.....So I am only getting up to about 14.5 psi or so. I used to get up to 16. 14.5 is a little low (target = 15.2 +/-0.7psi). My question is, shouldn't the ECU make adjustments to keep the boost in the proper range? Or would it require the addition of a boost controller...

    Hello, about a month and a half ago i installed my boost gauge line on the left of the intercooler on a hose and when it was installed here the psi would only reach 7-8 (PIC Boost1) I have a 2004 WRX, which i'm told should have around 13 psi. so a very very reliable friend told me that the...

    Does anyone know how to actually calculate how much boost my car is pushing. The boost gauge goes up between 1.0 and 1.5. So roughly how much boost does that calculate to? Any takers on answering for me?
