During my vast research for the best S/C for my 88 LX 5.0, I have come to the conclusion that the ATI procharger P1SC is the way I want to go. But then I second guessed myself and started checking out other ppls mods. Almost every foxbody with a S/C is using a paxton, powerdyne, or vortech. I see a considerable difference in price whereas the Procharger is more expensive, but is this the only reason noone uses it in fox body mustangs? Or is there something I do not know about that makes the Procharger not as good??? I would appreciate any help on this issue. I would hate to buy a $4500 Procharger only to find out I should have bought the cheaper other. THANK YOU and sorry bout the long post.
