Good power...but did your dyno operator notice that run 0 has a correction factor of 1.01 (adding 1% more power for correction based on air temp/pressure/humidity) and then run 10 has a 1.07 *adding 7% more power correction less than 1 hour later? Seems odd to see such a big swing in such a short amount of time.

He didn’t say anything to me, I didn’t even notice it.

Little low on power I’d say, other have reached 10-15 more hp. I just need a better tune. As far as mpg goes, it’s not the best as you’d expect, around 150-160 miles I’m looking for gas, and that was on a road trip on cruise control running 70-85mph most the way on the 370 mile trip.
70-85 is a broad range to me…for trying to nail down mileage…

Agreed, it was just what I was cruising at. Wasent looking to hold a specific speed to get an average gas millage:

Short update: I have put 15K on the new build with really good results. Did a west coast swing last June. 6600 miles in 2.5 weeks. Cruising at 70 still nets 40 MPG with no headwind. It starts dropping fast with headwinds or jumping up to 80 MPH. Either will drop it to 34ish MPG.
I have mine set at 10 PSI max. The bottom end would take more, but I haven't been able to get my clutch to hold lower RPM boost. I have upgraded to Rekluse plates and fibers and added the SE HD pressure plate. I had already added the flyweight pressure plate cover that applies more holding force at higher RPM.
To keep it from slipping I just drop down into 4th and roll into it. Tops 100 MPH pretty quickly in 5th!! Works great passing semis on two laners.

Stay safe this summer,

Seabee
