Please advise on what RPMs you guys use. I have had this completely set up on my stepdad's LMM and it worked, yet on another '09 with "the" newer OS it never kicks in. Typically on the last two trucks I set this up on, it would kick hard in T/H as it winds down from the higher gears on decel.

Since it doesn't work on this newer one, I suspected the infamous Transient T.V.P. table which doesn't exist in any other OS, so I copied and pasted the Low Altitude table in there with high hopes. Nothing. Then I though that maybe EGR was somehow active keeping the DSP Vane Position table from being used (since in DSP there is only EGR Off) - so I took some further steps to disable it. Still nothing.

Then I observed that during most of the test drive as I am expecting the exhaust brake to come one, I am at RPMs much lower than 2200+ set in the tune, mostly hover around 1500 rpm. So common sense would say that my RPM settings are simply too high (I will post table a little later.)

But on another truck truck it worked like that??
