    2010 2500HD trans tuning

    There any guides/FAQs on tuning the '10 2500HD trucks? I was looking to tinker with mine a bit, reduce the torque management some and speed up the shifts.

    What?

    Looks like spam.

    As far as facts and guides. I have none. I can tell you though that i dropped shift times to 0 and increased trans line pressure. Also disabled all TM and its a completely different truck. Oh and got rid of the throttle delay

    With the Allison you can not increase line pressure with tuning. You have to go inside the trans and do the mods. Also you do not want to remove defuel or TM you will end up with a tie up on a shift.
