Stuck at 14.2 psi of boost
I just finished up my head gasket job and got it running. Me problem is when I took it for a drive it will smoke way more than before, specifically at low rpm. Iím looking through everything with a scan gauge and everything looks good except the boost pressure is holding at 14.2 psi. It doesnít change at all unless I unplug the map sensor then it drops to 4 psi (so shouldnít be the wiring?). I know the whole atmospheric pressure is ~14psi thing but it doesnít change at all if I take off, idle, power brake, shut it off. I definitely donít have a boost leak big enough to this ether as it has way more power than if it wasnít getting boost at all. Should I just say f*** it and put a new map sensor on or is there something I might be missing?
Also, are the two ďmapĒ sensors the same? I might try switching them and see if anything changes.
