i was just wondering what they do when they port our superchargers....and what does it mean when someone says they have an apten supercharger or a steigmeir one..i read on the apten site where you send them your supercharger and then they send one back...is it the same stock one or is it different..and what do they do to it..they said it looks like the stock one so i am assuming that its a totally new one...i am going to get the charger ported and just wanted some help..thanks guys
