mechanical boost gauge problem

Recently i installed a mechanical boost gauge on my 02 coupe. My boost gauge reads right at 0 when its off. When i turn the car on it goes to 20in hg, but at full throttle it reads 0psi. I had a problem with my bypass valve earlier so i thought that was the problem and it wasnt closing so the supercharger could build boost but it seems to be working fine.

Any suggestions to what could be the problem? Could the gauge be faulty?

I no longer have the engine code for the bypass valve. I reset it a couple times and now it seems to be working properly.
