Default Help: 2004 boost pressure gauge not working

Hi all!

Hope someone can help me out. I've been looking all around online for a possible fix for my boost pressure gauge not moving.

I read online that it could be the sending unit so I replace it with a new - Stewart Warner Performance Gauge Sending Unit 82504-F but that didn't fix it ....

So can it be:
A grounding issue? If so, where should I look?

The Boost bypass valve? Any ideas on what bypass valve will work on the Supercharger Series IV? Link to buy a new one?
