Of course the catless mid pipe is probably also a contributing factor.

And what were the A/F numbers running?
The belt was slipping before and I was only seeing 5psi. I changed the tensioner and there is no slipping at 6.5 psi. I went ahead and ordered a 3.70 pulley. I want more boost. I'm a manual by the way.
