Typically going that lean from a known good blm/fueling would indicate vac leaks or possible fuel delivery issues. Because I had him check for the latter, I think in Waynes case the aftermarket maf is calibrated differently. I have tuned others cars who had to replace the MAF (with a gm version), but I would only see a couple of point deviation and nothing of any huge significance. Bottom line in this case is that it's going too lean/edgy for my taste, and I don't want to see anyones motor get hurt. |
