And that's where I left it last Saturday, didn't have the right size belt to go with a smaller pulley, so picked one up in Sunday and will be looking for more power later this week.
It also might be time to consider adding some more exhaust components. I'm not looking to lose the stock cats, but I may add the shorty headers I bought a couple months back to see if they have any benefit.

Excellent info! I know you said shorties but here is an interesting article on Long Tube Kooks to the stock NPP but using the HF cats instead of the green cats that they mention. It was suggested for my build.
