I run the MAF-T and i love it. The MAF-T translates from our stock AFM to the GM MAF. I have mine installed in my intercooler piping, post BOV, that way I can vent it to the atmosphere, with no stalling, and less restriction than the stock AFM. Besides the obvious, i also noticed major benefits with gas mileage.
You will not need a fuel pump or an afpr to use maf-t, but they wont hurt. A wideband is recomended for WOT, but it is not necessary to get the car running.
I am running an aftermarket turbo and fuel system, and i find it very easy to tune with just the MAF-T and my wideband, I don't even need my SAFC. I am pushing just short of 400hp, and I dont see myself switching from MAF-T.
