    Its a strong engine, may have had a headgasket under warranty if it spent its life in Toronto area. PM me the serial and I can check out the history, never know, I may have worked on it.

    Ok question about standard cat uprate. If I go in to get an uprate, do I just ask for standard 550HP file, 550 heavy haul or something like that? Or is there just 1 option for uprating. I always see something about a heavy haul, brake saver...etc so was just curious about that. Would love to do Mr.Haney's just so far away and afraid my T2000 cooling would never keep up
    Peen.........I just tried to post a long answer to your inquiry, but lost it to the great world of the lost internet. I'm not going to retype it.

    There are many options to what you can do. If I remember correctly I sent you a PM awhile back with my contact info.........give me a call and I'll explain the differences in your options, both with a CAT uprate, a PDI uprate or what I can do for you

    My preference would be one of two PDI tunes with your cooling capacity of the T2000 for the best in fuel mileage and a slight power gain above a stock CAT 550 hp uprate.

    Also run a 5EK. 28psi boost. Exhaust broke off the other day. Thought truck felt "peppier" but figured was just in my mind because of the noise. But boost gauge showed 31 psi. Dont like a loud truck, but i believe that makes a good endorsement for opening up the mufflers?

    boost

Engine doesn't feel weak I can pull people on hills with 80k lb's, just curious if it should have more boost and power.

    Serial is 6NZ62807

    And whats the personality code 134 mean? Thanks!
    my boost is 35lb.
