I'm running a 3.1 and have a 2.9 in the glove box. I'm gonna wait til I get some exhaust on until I swap it out to see if I still have the 7 1/2 psi. I was hoping to show 10+ psi next time to the track, but at the rate I'm going, it's not gonna happen.

By the way ... I'm still on a 5.3 and showing 7.5 psi with the 3.1 pulley.

 

That is one cool video, the headers sound great too. I might be buying myself a set for my truck, laters The Bandit-Z....
