really recirculating valves aren't for keeping the pressure up, they simply don't screw with the fuel tune on a car that comes with a draw through MAF sensor. Any type of blow off valve or recirculating valve is only there 2 do one purpose and that is remove pressure so the the compressor wheel doesn't go into surge (which allows the wheel to keep spinning faster/longer so boost stays up) it's not recycling the pressure it is allowing the turbo to get back up to pressure faster.

On a rear mount kit you want to keep the exhaust diameter small like 2.5" in order to maintain velocity. they also use relatively small charge piping which is no bigger than the outlet of the compressor housing in order to increase boost response. Honestly i don't think we have a large enough engine to support a twin turbo rear mount setup, maybe a single rear mount.

All points well taken. Bear with me, I wrote them a long email and if I do not hear back I'll call tomorrow but trust me when I say you'll like the outcome. We'll start a whole new thread on the situation once its confirmed.
