Quadra-jet Performance
ok, i have the Q-jet, and i have heard that its CAPABLE of 750cfm...but it only runs at what.....600?? iv heard something about fileing down the secondaries or something like that to make them open more so you get more CFM's...this true? and how do you go about doing this?? will it keep my car emissions legal?

There's a tech article on it.
Won't affect emissions, since it only modifies the secondaries.
