  1. one thing is missing here, what size drive tires do you have? 4.42 rears with 11R24.5's is pretty much the standard here and I averaged 6.8 doing the math in my 04 Granite, my friend does the same with his tri axle, all grossing 74,000#. actually two things are missing, what trans are you running? OD or Direct, Mack or Eaton, .74 or .68 or .62 OD? all this comes into play. Id leave it alone, you got almost 6mpg letting it run all day sitting in traffic and I always shut ,ine off if it sat more than 5 minutes so i saved a ton of fuel there. Also just because you are using half throttle doesnt mean your only using 350hp, you have more torque than stock now with the pump work and injectors and the torque is what does your pulling down low. I think if you just ease into the throttle and let the truck do the work, keep it under 20- 25# of boost (unless you can pass a cat) youll be happy with it. I had 4.42 rears on low pro 24.5 tires in my 84 Superliner, E9 440hp V8 turned up a bit with a Mack trtxl 1070 . It was geared steep for the highway and I pulled containers and dump trailers but if i did more driving under 55-60mph than over 65 i averaged 6.2-6.5 but I never used more than half throttle unless I was teaching a pete a lesson on a hill. leave it alone and give yourself some time to get used to driving it, youve onloy had that done two weeks now, itll take time to learn how to drive the new hot rod parts to get the most out of them.

  2. Need measurements please- highest point (looks like the stack)

    Furthest point in front to furthest point in rear (tip of frame rails?)

    I have tight quarters. May consider tossing an offer if it will fit inside. And does it get along with F.W.D.'s??

    Have you had it on the highway? Whats the top comfortable speed? How many miles on it, and do you have any service records? How about the Mack factory records?

    fwd ill get em for ya tomorrow hopefully, I just worked most of the day for the railroad and came home to get my truck and hauled two pieces of machinery, I is tired!

    I havent had it our on the highway, the stack is a rigged up job because the former owner didnt like the weedburner but that is what should be on it, its pretty darn small for a truck, I have room for it a gator and plenty of other stuff on my trailer. I got no records on it, havent hit the mack museum up yet.
