Decided to compile some data in Excel and see a visual representation of what the mods do. The blue line is the stock 3.80" pulley with the cams advanced, causing them to close early. The orange is the stock pulley and stock cam timing, and the gray is 3.48" pulley with stock cam timing.

I don't think the belt is really slipping, I need to look at the MAF frequency and not the boost gauge to really tell. The MAF frequency will jump around, it did it even with no supercharger.
