Don't worry about the STFTs, but you want the LTFTs to be 0 or slightly negative at idle & cruise. They should go to 0 at WOT. MAF ends tend to lean the car out, which result in positive LTFTs, but they have been known to cut up to 1/4 off your ET, so IMO they are worth tuning around.
Monitor your KR at WOT. If you are getting any steady numbers, you NEED to change something. (fuel, timing, parts)

Predator does not have the coverage you need
to deal with MAF ends / ported MAF. You need to
recurve the MAF table for that, you can't, only
the custom tune route will do it. Forget the ends,
especially on an A4, unless you want to go custom
tune. Go to DiabloSportTuning.com and see about
what that entails.
