Replace tensioner(order 2 keep a new one in the car along with 3 new belts.Now grind off the tabs on the new tensioner with a dremmel tool not a mash hammer & mason chisell.Also check & see if the tensioner is in the middle of its travel distance(probably not).You will need to move or replace a idler pulley to make the travel distance of the tensioner centered.GI Joe's are reichard tensioners,they will not work easily on are KB blowers as we would have to move the PCM.Atom @ ST Motorsports has a Franken tensioner for our set up.Trust me i have gone through 4 tensioners,3 belts,one dent in my hood from the underside of the belt whipping off.Your car is a manual trans correct??The new idler pulley has to be made larger i think,but not sure.
