Another data point...
I had my TT GIAC chipped, fitted Milltek exhaust (with 100 cell cats), new headers, replaced the DV's etc - all usual stuff but no V-Flow airbox. The MAF failed within 100 miles of these mods while at WOT. Coincidence ? I don't think so. Changed out the MAF and now 7000 miles later still as good as new - actually better :-)
Moral - MAF can fail even at a moderate state of tune and without the V-Flow being part of the equation. Maybe the V-flow just aggrevates an underlying weakness ?

I feel for you guys with the maf problems.I have had three EVOMS kits in my car(gt640,gt700,gt800r)since 2004(all w/v-flow oiled and dry filter)and have yet to blow a maf.Am I just lucky or is this something car specific?EVOMS now has a waffle like insert in the airstream that they are trying out, but why hasn't my car ever blown one?I can understand how this can become very tiresome.

The MAF should blow, no matter what box is in the car, with a pair of GT28's sucking air past it - shouldn't it???
I have never seen the V box first hand.
I have seen pics. 
I would venture to say this ............. Remember the law of the weak link. Well with these motors it is the restriction instead of weak link. It is my guess the V tech allows for better flow. Once installed something else becomes the restriction. This is probably where the problem lies. I do know the stock MAF is rated for 485 hp. In addition Porsche seems to a 30% or so safety factor built into their products.
