My apologies. Throughout the course of reading all 5 pages I some how forgot that you traded up to an iS. I don't know how an intake can Be limited to a certain boost level when the turbo inlet pipes are the same? The only AFE units I've seen we're the original open elements. They are even smaller than the stock airbox. Any one who has removed one and tied to reinstall the stock box knows that. The stock box won't fit into the factory inlets. I've had the best luck with a heat gun to soften them up and be able to let them flex. At least the unit you're testing and the Dinan offer true cold air, which is a must IMO.
Previous dynos aren't necessary.
