with going to a FAST 90 mm Intake and 90 mm Tbody? currently have a stock ls6 intake shaner S3 ported stock tbody smooth bellows and MTI lid, what kind of gains would i expect to see from the swap? I assume i would also have to do a new bellow TSP 85 mm lid and 85 mm LS6 maf as well to maximize the combo? another problem id run into i have the NX maf kit that replaces stock maf ends i wonder if NX makes a 85 mm version of it? so anyone justify doing this combo on a HC car (Tea heads FMS cam 440rwhp as is)

I think with your setup the LSX 90mm setup would give you some decent gains. You wouldn't necessarily need the 85mm lid/MAF, but I doubt they would hurt any Just make sure you get the LS6 85mm delphi MAF, and get it tuned for. otherwise your car may run somewhat shitty.
