    Default Allison LB7 line pressure adjust?

    Can the line pressure of the Allison be adjusted by EFI Live? I want to get just a bit more pressure into 5th. Is it possible?

    If so, what tables would I need to adjust and which way. I am getting better at the ECM, but I am afraid to dig into the TCM without someones guiding hands.

    Thanks,
    Tony

    Ok thanks. I found out on both DP.com and TDG.com also.
