Topher,

I have a similar setup as yours. I'm running the V & H Powershots on a 2005 Silverado with the BAK filter and jets. Also, have the Baron's ported manifold and AIS removed. I generally get around 50 mpg (with stock speedometer and no adjustments). My jetting is a little leaner than yours, at least on the lower end. Main jet is 172, 3.5 on the clip and around 2 on the PMS. I started at 4 on the clip and the bike ran well but my plugs looked like I was running a little rich. Went to 3 on the clip and bike would just not run well at all. Added a .020 washer to lift the needle half a step and that seems to be a sweet spot, at least for my bike. Oh, I also cranked the accelerator pump duration adjustment down to about 1 turn out.

On one trip I actually averaged 58 mpg. That was over a couple hundred miles where because of road conditions never was able to get much faster than about 60 to 65. Generally, I'm averaging around 50.
