    Default Top Speed Limiter Qs

    Tuned a 2001 CCSB Dmax/Ally 2wd and a 2004 CCSB Dmax/Ally 4x4.. Cant get either of them to get over 111mph.... Whats the deal?
    Ill post up both tunes when i get home. But i went to the Speedometer and changed everthing to 130mph. Neither of the trucks are hittin the rev limiter.

    Both guys love the tune and fuel mileage they are gettin now. I did the 20-20 Tow tune on both of them. And have been tweaking on the 2001 2wd since he uses his for a Long Range Work Truck. He went from 18-20mpg, and after a little tweaking he is gettin 21mpg now..

    Check Injection Timing C for revs,
    Check Rev Limiter Parameters
    Check Vehicle Speed Limit
    Check Throttle Based Injection Quantity

    Try those, but I would be more than happy to look at it for you if that doesn't help. Log it and check fuel timing etc etc it has to be there somewhere.
