I ditched the stock tensioner and used a jeep tensioner that mounted on the bottom bolt hole of the left side mount. You will need a 5.5 m10x1.5 bolt to run through the tensioner, front side plate, round tube and rear plate and into the stock tensioner hole on the left side. It is way strong and you have an alternator that sits lower than the throttle body and on the passenger side of the engine. Wow that sounds confusing but hopefully you get what I am saying.
