    Exclamation HELP! low boost, possible related to horn?

    Hi i just bought my 2002 WRX with 58k on it last week and i love it. Last night however i installed a boost gauge, only to find out im only running 4psi!! the gauge is hooked up to the blow off valve line which is directly ported to the manifold so it should be giving me an acurate reading. now i have checked and i do still have the brass pill that is in the hose comming out of the turbo. now also i keep blowing the horn fuse. i even put in a 30 amp fuse at the dealership to set my remote and that blew. so obiously there is a problem in that circuit, could it be related to my low boost? please any advise you could give me would be great!

    boost is mechanical, not electrical. The horn situation, bring it to the dealership assuming you still have warranty for the 90-days. If you bought it private.....well i dont know how your gauge is hooked up, but if its attached to the cigarette lighter, that is also the same fuse for the mirrors and horn. Check into those connections.

    Check your fittings on your boost gauge, make sure the line isnt crimped, make sure theres no holes either. You have it hooked up right, just run over everything.
