I'm not buying prototype until someone personally has tested it. Not from a manufacturer or some sales guy. I want a use case scenario with video of stock evo before and then after.

There are many reasons. This is a cast manifold so there are advantages like better thermal management under the hood and less likely to crack. It can use a stock heat shield. It is approx 35-50 percent the cost of a tubular manifold and if the runners are a lot larger could possibly help with higher HP stock frame turbo. It is not much more than a ported stock one and looks a lot nicer so if no other reason it is a lot prettier. This combined with the new turbine housing could basically make a T3 setup obsolete. They might be able to make an HTA 86 sized turbo with the bugger turbine housing that will make 800whp and spool as good as a twin scroll t4 setup. The possibilities are there. Hopefully the realities are close to the possibilities. I know Curt Brown made 800+ on the DSM version with the bolt on housing HTA 86.

I'm getting lucky with Amazon and the Xbox One not charging till it ships. I understand that FP can't do the same as it's a bit different....

A better flowing manifold will lower pressure at the exhaust valve but won't change pressure at the turbine wheel as the turbine wheel and wastegate determine the pressure there. If anything, improving exhaust manifold flow will increase pressure at the turbine wheel.
I suppose FP could answer the question though, as they likely have had pressure taps at both ends of the runners.
