Sweet2002, I do think Bigger Intake Manifolds would benefit anyone running stacked as it should lower your boost a bit and give you more adjustable A/F. Obviously once you max the charger then everything else is moot, so bigger intakes should help our little charger efficiently.

I think I read in another forum that manifolds will lower our torque a little but helping it breathe will give us some top end HP. My torque is enough to be almost unmanageable so giving me some up top is welcome. My exhaust helped open up the curve some too.
