Here is my CVO King,  259E cam, 10.5 HD pistons, Head work By Dewy, compression set for 10.8 to 1, HPI 55mm throttle body, 5.1 injectors, woods lifters, and Fullsac DX head pipe with 2.25 baffles.  I average 45mpg on the Hwy.  Range is 240~260 on a tank.  My best was 48 mpg.

Those are really good numbers on hp, tq and mpg Dave. I was hoping for something similar with mine. I would have been okay with mpg in the high thirties. Generally if an engine is built right it'll be more efficient and get decent mpg, unless it's a screamer and you dog it.

A Friend and I built the motor, had the head work done.  Then had Doc in FL tune it.  I believe the good numbers and MPG are a direct result of Doc Tuning the bike.  He spends several hours tuning, and does a much better job than a dealer.  Torque really should have been a bit higher on my bike.  I feel it was due to the packing blew all the way to the back of the mufflers and did not know it.  Friend has the same build, and has 3.5 more foot pounds of torque and the same HP.  I now have screens to hold packing where it belongs so I think it would do a little better.

My dyno chart below. Max 105.72 hp and max torque 114.57. And the hp comes in late.

Looks virtually identical to mine!
Swapped out to Tman 625. Pulls TONS better down low, but kind of lays down up top above 5200
Overall it's a much better riding bike. First road trip of year coming up this weekend, see how mpg's do,,

Got the bike back from Steve at GMR and couldn't be happier. 125 hp and 130 tq. In Sturgis and put 300 miles on it yesterday and got 44 mpg. I know you always get better mpg up here than in Houston but that's still great. Bike pulls very hard. Thanks Steve!

Same kit installed on my 210 CVO Ultra.  102 hp and 110 tq 35 mpg two up. Part throttle response is awesome but motor is always on the edge of detonation so a little bit of race gas is used to controll it. Many hours of Dyno time to get it as good as it is. It may be the VH X pipe contributing to the poor performance.
