Lol no stock psi
Problem is map sensor pid in hp tunner is reading wrong not the sensor inself
The map sensor reads absolute pressure. That is why it is called manifold absolute pressure. Turn the key on without the car running, and it will read 14.4 to 14.6 psi. So it is reading correctly, you are looking for boost pressure...to get that from a map reading, you have to subtract your barometric pressure. Qck2spool is right.
