110mm Maf 
110mm Maf
So far maf have been working grate for me. I just put bigger turbo so I need more maf rum. It is easy to tune the maf.
I say ditch that thing and go speed density.

If you can make the MAF work, there is no reason not to use it. When you do a MAP tune you are cooking in the VE into the surface. If something changes you could go richer or leaner at the same intake pressure. The same condition on a MAF tune and the A/F ratio is still spot on.

Richer: The air filter gets plugged up or the exhaust hangs low and gets smashed partially shut hitting a bump. The engine now flows less air than it used to. It will run richer than it did previously.
Leaner: Air filter falls off. You now have an extra 50hp of air in the system that you didn't previously on a 700 hp engine. You'll be that much lean.

This. If I remember correctly a slot MAF in a 4" tube will support ~1000hp of flow.

You could also say, maf gets dirty and it runs a point leaner.

There are pro's and cons to both.
I changed cam timing on my turbo Audi a couple degrees. I had to retune half the map. Had it been a MAF tune, I wouldn't have had to do anything. Up to a certain point I would prefer a MAF tune. Once you start making really big power it doesn't make much sense though. There just gets to be too much math going on.
