Those sound like the MAF electronics are
putting out an overrange (high) output
frequency. MAF porting should mess you up
but in the other direction, and not to a code-
setting degree. Did you do this with the
electronics still in place? If so you might
have smegged one of the little sense
resistors?
All together now...
"ported MAF... Baaaddd".

agreed if you have a4 dont port the maf. m6 maybe?
i have had a home ported, TR ends and 85mm maf and none of them help me... only hurt my times.
but not all cars are the same... if your running really rich then yeah ported unit might help only becuase it brings the a/f ratio closer to stock...

The 1-2hp gain from this mod is not worth the trouble.
