I swiss cheesed my airbox last night (see sig for pics), re-installed my Amsoil filter and away I went. Previous to the mod I could never get more than 19.5 PSI boost (unloaded). After installing the modded box i am getting 20.5-21.0 everytime i mash the go pedal (unloaded again). Has anyone who has hacked their airbox noticed anything similar????
