okay i have my jackson racing supercharger and well just recently installed a boost gauge after all these months anyway last week my car ran fine and all but now my gauge is reading 10 psi . i have no idea why and my car is also runin lean at full boost .last night i got on it and a cel came on . i pulled over and scanned it with my generic obd ll scanner . this is what it read. manifold absolute pressure / barometric pressure circuit intermittent . now i ahve no idea wtf that means so can anyone help oh yeah i now hear a weird noise what at first sounded like my head but im now positive its the blower .think i fucked a blower blade or something grr i hope not

 

oops doesnt say intermittent it says high input

 

Your map sensor is seeing boost. If its still the OEM sensor, its not designed to see more than 11 PSI, and its possible the ECU detected some boost spikes that were around 11 psi.

 

well heres the problem i only have the 6 psi pulley set up . i have never changed it ive had it since new and i know ist what i have on . what i cant understand is why my gauge is now reading 10 psi . yes it is the oem sensor.

 

clogged cat?
