and though the MAS doesnt create flow issues, it does, to a point, create placment issues when plumbing for a custom turbo setup, (for me this would be a single turbo setup) where you would be splitting a single 4" intake to dual 3" then finding room for two pop charger/air filter combos+ the MAS. Of course it possible to fit all that, but to place them where they would be "fairly" equaly spaced from the turbo, as not to create and "unbalanced" situation drawing more air from one airfilter than the other. unless this would actually cause less of a problem than im predicting (hhmmmm scratechs chin for a second) im not trying to argue or "flame" im just looking for the better way of setting up my turbo setup to work most effiecently, and of course create the most power "effiecently".
