Bad MAP sensor?

[614talon90]

I have been trying to figure out an issue for months where my car is totally leaning out half way threw boost. Tonight I did a log and after reviewing it saw that when i was at just 12 psi of boost the reading from my MAP sensor was 31.5psi. At that point my boost kept climing and my MAP sensor stayed at 31.5psi and i leaned out. Is that reading correct? Is my map sensor bad? BTW if it is not obvious the car is running SD only and that is the way i bought it so ive trying to tune it. Any insight would be appreciated. Thanks!!

Attach the log! What kind of map sensor? What does it read with the key on and engine off? Attaching the log would be the most helpful though.

I course I thought of doing neither of those. It's a gm 3 bar. I will post a log.

Dead cold key on engine off it reads 17.9.

From owning a GM, shouldn't it read the current barometric pressure. 17.9 is like a massive tropicalstormtsunamihurricane

Ya I guess it stops reading after 12 psi of boost like its maxed out.
