It may need a chaincatcher, may not.
In answer to the OP question about the Truvatic elita crankset, I think it is fine and is not the problem. I used one without issue after I switched shifters. If it is ISIS, thats a bigger problem as finding BB's that last longer than ice cream is difficult.
Addressing you original problem:
If the cable be attached to the FD with the uncut side of the cable on the outside (away from the seat tube) of the attachment screw then try changing it to the inside (closer to the seat tube) of the screw. This will change the leverage and increase the movement of the cage for a given cable movement.
