yah i figured that out later, the car kept having these weird lean spikes whenever i would log, it would be right in the middle of one of the upward swings everytime, just enough to screw up my averages.Originally Posted by black06g85

I just played with my low end maf table values to clean up the fuel trims at cruise and idle. It stays @-2.3% LTFT or so with the 79lb/hr injectors.
