2013 6.7L.
Can anyone help with why the turbo is not engaging while driving?
I know that it has not failed like it did 3 years ago because the exhaust brake works like a champ.
I am doing the 200 mile relearn for a Revmax transmission.
I have the DRD tune for the trans on the MM3 and I can watch all the gauges.
Yesterday I had boost pressure registering and today just zeros.
I suspect that this is an issue with the ECM not maintaining the entire tune in its little brain.
I had ECM and tune compatibility issues in the past and replaced the old tuner and file with the new tuner and file.
Before I go off and rewrite the tune to the ECM I would like some input please.
Also will a reflash cause me to restart the relearn process on the trans?
