Lookin' good. Give some more details on stock s/c and after you did the pulley. I realize you don't have a dyno but I'm more interested in the seat-of-the-pants difference before and after.
With the 2.8 it wakes up the supercharger a little more, you feel the supercharger/truck pull a little harder. It's by far not a huge increase but enough to feel it.
Now if you went from stock to a 2.55" you would really feel a waayy bigger gain from stock boost 6 psi to 10-12 psi
