Map sensor question

I have a watchdog gauge monitor which generally does pretty good, but my map sensor only reads 23psi of boost, so that's all it shows on the watchdog. Is there a way to get a heavier duty map sensor that would read, say 35 or 40 psi so it would show my actual boost?

The stock map sensor is able to read around 40psi. Maybe you are only making 23psi or its just bad

well my boost gauge goes up past 30 so i dont think its a low boost problem. ill have to try a new map sensor and see where that gets me.
