Well, the first but not the only 2007 Shelby with a pulley change, we have another coming that also has a pulley change. As you now in the past we have seen 2 Shelby's go 490's hp and 480's tq with just tune. This car made 519hp and 536tq not to bad for just a little boost up grade. We saw 40+hp and 50+tq gain across the board:cool: . But when the car left that night it looked like it picked up 100+hp and 100+tq:burnout: :flash:
