Ok ive been reading and have developed a few questions. The gm mas what exactly does it do and does it really allow for venting or is this a bunch of b/s. Reason I ask is because i was looking to buy an injen intake
for my car but read somewhere that if i bought the gm mas that venting is possible w out all the h/s side effects. Anyone have this or know about it.
ps. sorry I know this subject is beaten to death but couldnt find any good threds on it!
