    I am wondering if someone else who has one of these can tell me what kind of manifold pressure you are getting when pulling hard and your mileage. I only have 16000 on it but am only getting 32 lbs of pressure most of the time and 5.5 mpg and I'm taking it easy most of the time.

    Close to 40 but with a '13 600/2050 pulling 170,000 getting 3.5 mpg. 35,000 miles. Roughly the same pressure when it was a 550/2050 and mpg was closer to 4.0.

    13 600/2050. Manifold pressure runs 32 to 37 under load and 30 while jakeing. Fuel mileage is 5.5 to 6.1 @ 86000#, depends on the weather and route I am running.
