And I would bump the HP down, unless you are hauling 100,000 lb loads. And like Nick said, a pyro and boost gauge, and never lug the motor, keep the rpm's up. I bet they dry started the motor, that is what my gut tells me by your description of how it was running when you got it out of the shop. The mileage sounds about right though, I get 6 mpg all day long pulling a dry van with a mid roof, no fairing. 18 speed with 3:42 rears. I have a factory 600hp set to 485hp, Rawze did the tune.
My oil pressure is 20 idle and 45-47 going down the road. What should I put the hp at 475,500, or 525 I have a pyro and boost gauge and watch them constantly. I run down the road at 1450 to 1500 rpm I pull most hills at 1400 to 1700 rpm. Since the work was done I did change all 4 actuators and 1 injector I don't. run heavy I always try to run as light as possible usually under 30k on the deck. Do you think a new set of injectors would help? I'm only suggesting this because I have already had a problem with 1.
