Hi, Do yourself a favor and switch over to mass air. You will be happier you did... My speed density was horrible after a cam and other modifications.. You are won't run right and you won't see what your car can really do. also if you gunna install a CAM, I would recomend upgrading your injectors but one size (#24lb) with matching mass air. your gunna be adding more air so you'll need more fuel or you'll burn up them headgaskets and melt pistons. I have found that using #24 injectors i gained MPG and the car was alot more responsive.. Also if your car is AOD car, mass air is needed cause you won't be able to keep your car stopped at a light cause of surging... take my advice.. MASS AIR!! good luck!
