I would look into trying an unported MAF sensor, and make sure the wires inside the MAF are not "dirty" with oil film or anything. You can clean oily film off with electrical contact cleaner or brake cleaner if needed. If you have access to autotap look at the LTrims to see if its adding more fuel or less fuel than actually needed, or post the autotap data here for others to check out. <img src="gr_stretch.gif" border="0">
