~CraZy boost gauge

[nizmokid]

I am having a problem with the factory boost gauge as it is reading full all the time even when off boost???

weird... the Needle is isn't getting stuck as when I turn off the car the needle drops. sometimes it will work fine when driving, but only sometimes.

I thought this might be something wrong with the car, as the needle shows high boost all the time the ecu might be using more fuel when it doesn't need it????....I could be wrong!

But I have a a HKS boost gauge and that works fine!!!!

any ideas on the problem????

Mine would go off the scale as soon as it was started (33), I never bothered to fix it & just got an aftermarket one like you, which worked fine.

Factory boost gauges are known for being pretty dodgey

check the vaccuum piping from the plenum to the boost gauge control box... just follow it...

I had the control box checked and that was fine....mechanic checked it, box was working fine!
