The point at which the MAP sensor takes over can be set using the support tool. I don't think it's designed to work under vacuum. So you will have to make sure the airflow you clamp the MAF signal at is a point where it only reaches that airflow under boost at. I say as long as you have a MAF, you might as well use it to it's full extent. Or use the MAF swap feature and just use a bigger MAF.
But keep in mind that the Preprogrammed E-Manage is password protected so you can't tune the program unless you reset the E-Manage, in which case you will lose the existing program.
As far as manifolds are concerned, I'd cut the flange. But that's just me. Better to prevent cracking in the first place if you ask me. My used XS kit came with a crack in it already. I had it properly welded, but it still cracked. I took much precaution with my new Rev-hard mani.
As far as stainless steel, it's a great material for manifolds. It is plenty strong. The only problem with stainless is that it expands a lot with heat. Reliefs for expansion are absolutely necessary. But properly made, it should be quite capable of handling the loads of any turbo system.
