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?

Still stuck on how to fix the boost gauge. Any suggestions or help!?

Does any one know what bypass value is used on 2004 Saleen Series IV supercharger? What supercharger do they use, Eaton or Lysholm?

Will this work?

Default boost gauge

Well if you did the sender and that is hooked up right, your left with a power issue or the ground issue. You are getting the variable voltage from the sender, but you are still getting actual power from I believe the gauge cluster. Correct me if I am wrong anyone. Also your best bet is going to the source and pulling the gauge itself but you have to pull your radio out and maybe your cluster which sucks. Never been in there on a 99 04 car, but you can only test the gauge by getting in there. Let us know. Oh take a look at the center gauge pod install instructions I believe they show an 03 04 set up.
