Wel'p, I drove it like I own it for the last week and after adjusting my timing and having my stock tires on, I drove 229 Miles on 15.74 Gallons = ~14.6 MPG. $39.50 Fillup. Better but far from where I would like it.
Next I'm going to get the BR diag to hook up to my laptop and see if I can make some more adjustments to the timing and maybe run Mid grade fuel.
