I have a 2011 386 peterbilt with a cm2250, 13spd 342 gear ratio. Pulling a 53' refer Average 5.9 mpg, 450hp went and seen Mr Rawze himself, great guy, he made a few adjustments, I ran it 10,000 miles, kinda hard the last 2 weeks, and my average mpg came up to 6.2. Thank you Rawze for all you do, and your knowledge and kindness to help others.
