    Its likely the case. I seem to recall my tuning has the pressure turned up to 180psi but I do not have the ability to confirm that unless @Double R Diesel can confirm from my files.
    Unless you specified otherwise, your MLP should be 180psi at WOT. That's how my tuning was on my truck. Factory is like 160ish? Ideally, 225 is the pressure you want, but that requires a VB upgrade.

    no VB upgrade here. Maybe soon, then again a g56 dually may be in my future.....

    Future plans: Fass, head studs, slightly larger tires (at least more aggressive tread)

    Unfortunately, it seems that the only fix is to replace the VB. I don't see anyway of band-aiding this issue. You may want to consider avoiding the OD gears until you can get this resolved; your fuel economy will suck but at least you wont have to worry about the OD clutches not holding.

    What setting have you been running your MM3 on? Also do you lock your truck out of 6th when town for the most part?

    I am on the 30hp at almost all times, and never have towed at anything higher than 60, and that was only once or twice. I simply use tow haul mode, I do not lock out 6th with the manual shift.
