New MAF for an a4 ok, i've heard so much stuff about people putting mafs on their autos and havin problems, wondering if anyone can finally clear all this up for me? and whether i should get one or not and which companies you reccomend? i was thinkin granatelli??? i think that's how you spell it, or slp. so any help anyone can offer would be greatly appreciated. thanks in advance. oh and mods in sig, ~450rwhp and a dynotune comin up soon after a couple more mods.
contact whoever is tuning your car and see what they recommend. you plan for spray to hit that 450rwhp cuz you wont hit it with the mods in your sig unless you add some heads.
The aftermarket mafs always seem to be more trouble than they are worth. Put that money towards the most important mod for an A4, a 3500+ stall converter and then heads or N2O.

Also a Yank 4400 will make you loose more dyno power not make more. It does make your ET's quicker though.
As far as MAF goes, I have a GMAF and never had problems with it. If you're spraying wet, then don't bother. If you're spraying dry you could get the NOS calibrated GMAF.
However stock MAF with ported ends is good for 600 horses and much more flexible in tuning, works good with MAFT so you can tune and de-tune for before and after track.
