The maf sensors aren't that different in the tabling that it would cause this issue. I know this from doing it myself, got sidetracked forgot to program the table and ... months later noticed the table.
It sounds like you have other issues. There is a tube connecting the EGR to the LIM. Pull it out and look at it where it meets the LIM. Pull back the piece that holds it to the lim and see how big the crack is...
