40-42 mpg is what I get with my CVO, I hope when they do the dyno tune the SG doesn't drop down. (Canned map V&H headers, Supertrapp & 255 cams). The canned map was installed assuming I had the A/C kit installed, but I don't.
I would think it to be running rich until I get the A/C upgrade.
Seriously, I'm surprised at the great milage. I hope it doesn't go down after the tune.
