Re: History of the 93.
I know when I had my vortech on at first I was only getting 2-3 lbs of boost when it should of been making 8-9lbs. I called vortech and the guy told me to put a socket with an extension bar on the tensioner pulley and said to hit it with a hammer to get it as tight as possible and it took care of the belt slippage. I couldn't believe how tight you had to get it for it to hold.
