    Hey guys has anyone on here tuned a Paccar Mx13 455 epa10 motor? I am curious to find out what power rating I am able to gain and still be safe. Diesel spec is saying 500 to 505 with emissions and off road performance up to 525 - 550....

    Have run this combo in a prior truck.
    It works well at the factory 485HP.
    The fuel and turbo curves are not quite matched up, tends to be a tad lean. Some one with paccar software can do the fix, just matching up the curves.
