I have an '03 cobra and only have a Borla stinger for mods. I don't really want to do the pulley and tune at this point. I was wondering if anyone has any information on the Granatelli mass air sensor w/filter? I wouldn't mind paying the costly price for it if I know it will out perform the other cai's. Also, does this sensor leave evidence on the ecu that the car has been tampered with? Thanks!
