DIC boost guage half filled WOT

**Perry125** · 09-13-2009

Hello, when i am full steam ahead, the boost gauge in the DIC only has half of the bars lit up?

It feels quick.. and i can hear the blower. is this just a gauge problem?

thanks

id almost bet 100 bucks that u have a vaccum leak. My T boot connection that goes on the intake right under the supercharger snout was disconnected and i had the same problem with boost indicator. If the leak gets bad enough it will throw a throttle position sensor code. Anyways there is like 4 or 5 vac lines if im not mistaken. just trace them all out and look for leaks or even completely disconnected lines.

Thanks, ill check it out.

I hear a noise that sounds like grinding almost since i put my intake on...

is that just induction noise or what? I thought you could hear leaks sometimes.

induction noise is correct, should be really loud on cold start then calms down a lil after it reaches operating temp. mine does it to when i get on or off of the throttle.

just get a real boost gauge instead of watching that useless DIC display.

Yeah not a bad idea, im thinking about getting a everything guage that displays boost and everything i would ever want to know.

So is that gauge not really even accurate?
