perrin big maj question

hi all,
i know that perrin has a spreadsheet on their blog about MAF scaling.

last time i installed my big maf. (didnt know it was big maf at the time. i wanted to get the 2.5, they sent me the wrong one) my LTFT went really crazy. and i was killing gas. (i think i was running lean)

will the spread sheet on perrins blog help with that? even though i dont have a custom tune.
currently running OFT stg2 uel v2.06.
