there is no brains in pumping your boost up on your already turbo car.....u can get some cronic power out of NA's....ported, polished, blueprinted, headwork, cams, stroking, ITB's, bigger fuel pump, high pressure injectors, EMS, ignition systems.....i could go on forever....if you did all that to an NA engine you would scare yourself
