    need help fuel issues

    The whole year have been running rich 11.2-11.9 some where in this range. With my static ppressure at 58. It has gotten cooler out and have turned static pressure to 60 or 61 and it running lean at 14.5-15.0 at 9200 RPM'S. I have 2006 RXP with a turbo running about 22lb boost. Any suggestions or if you think something has gone wrong please help as I am at a loss. Thanks

    Sounds like either yout fuel pump or o2 sensor has shit itself? Was the pressure dropping off as revs went up? This is a sign of a pump not being able to flow enough fuel.
