the vane position in your file was that an attempt to do an exhaust brake?

[funnyLogan12]

yes, the vane 95% vain position on 0-5 mm3 between 2000 and 4800 RPM is supposed to be a turbo brake. I found it in some old threads about tow tunes.

the way I understand it is when in tow mode the truck will go into downhill assist and downshift. upping the rpm to help slow the truck with less actual braking and increasing the vain position adds back pressure to make it more effective.

Correct I use it on my 6.0 Powerstroke in almost all of my tunes. I don?t do Duramax a lot but I don?t see anything wrong in my eyes.
