I've been searching around the forum a good amount about this topic and I seem to only find people talking about this but no one following through to the end. 

I have a 1.8t a4 and i'd really like to move the maf to the intake side of the motor so that I can worry less about leaks and intercooler tubes blowing off (which is a big issue currently haha).  I'm running a t04e turbo so i'd be maxing out the stock maf anyways.  Right now I have the maf disconnected and it actually runs pretty well but is finicky and from what i can tell isn't actually reading boost levels, which scares me.

There's a couple people near me selling pro-m mafs but they're calibrated for mustangs with varying injector sizes.  Would I just need to contact pro-m and ask for there data points for that maf and then plug them into the maf scaling table?  I think i can get one for $50-$100.  I haven't researched this part much because I haven't decided what my actual plan is yet.

im running a blow thnru on my vr6 turbo using me7.1.

Vr6 swapped Audi or gti/jetta?  (Just curios)

And how does it work out?  I think that since your car is NA to start with it might cope better, but I have no info on this.

In your opinion is it worth it?  Most people on here stick to the normal draw thru but I see a lot of advantages to it.  I just don't wanna invest a lot into this and then still have a car that runs like it does now.

I already have the pcv disconnected from the intake.

To me, it doesn't matter much which maf method I use to tune.  My main problem right now is that when I plug the stock maf in it runs super lean at idle, but bringing the rpms up some brings the afr's to a reasonable 14 or lower.  I have a forge splitter which worked fine stock.  I've moved to about 10in from the throttle body with the recirc hooked up.  Its possible I have a small leak after the maf but it can't be very big.  Any thoughts on this? (Its a draw through setup)

Since my maf setup gives me problems and I have to drive the car everyday, I've been driving with it disconnected.  The problem with this is after I get to 22lbs of boost the throttle closes and if it goes back up that high again it puts the car into a soft limp with no codes.  Throttle opening is limited to about 30% from what I can see.  Is that from going over the map sensor limit?  Or maybe torque intervention?  Although I doubt its that fast.
