Yeah, but I think the tuning references the air that's in the manifold, up to the TB. Fact is, this VI opens up a pouch inside the manifold, changing the manifold. Outside the TB is another set of parameters altogether. It's all speculation, but we'll see. No, you'll see.

I don't believe that is entirely true. This manifold was designed without a popcharger or CAI in mind, so a stock airbox may provide the best intake characteristics. The whole idea behind the VI is that it is a resonance tuned intake so turbulence/pressure drops were taken into consideration as well as the air velocity. The CAI lacks the top end of the pop charger, but if the pop charger flows too much faster than the VI was designed for there could be some power loss as well. Basically I'm not saying that the pop charger won't be the best option, but the intake was designed with certain characteristics in mind and if you change them too much it isn't always a good thing.
