Which Idler Pulley?

RE: Which Idler Pulley?
According to MotoBlue, Saleen, and the other companies that make the UD pulleys, it's supposed to free up 'robbed' horsepower from running the electronics. Since I put mine in along with a CAI, throttle body, and tune, it's impossible to tell if there's any direct HP coming from the pulleys. It's a sound theory though, so I think they provide some benefit. Still, the most they give is like 10 HP.
Oh, and about the tensioner pulley specifically. The new idler pulley Motoblue supplies is supposed to produce less friction on the belt, allowing it to travel faster, which is where the extra HP comes from. It's the same with any other idler pulley on the belt system though(there's 2 more).
