    Ive got a 2007 4900ex with a 14 Liter series 60 Detroit and a 10 speed. Been watching the DataStar today and noticed that I can get 100% engine load in 9th, cruise or pedal. But in 10th it won’t go over 94%, doesn’t matter if it’s with cruise control or pedal.

    Is this a setting in the computer? And can a shop edit it so it gives 100% ?
