I think you are like me , want power , dont wanna spend ALL your money to get it , I debated them all KB , procharger , paxton and vortech for the last six months and called Dallas mustang last week and ordered the vortech for my 2002 Gt , $3140 plus shipping , it will be here tomorrow and I am going to put it on wednesday and if i dont finish ill do the rest of the install this weekend . paxton is cheaper but only 100 bucks and the vortech is easier to upgrade later , I also have an extra 300 to 500 set aside for getting it dyno tuned after its on , the reason i didnt get a kit without a chip is because i will have to drive it to get it dyno tuned which is a must with any supercharger .
