Are you even boosting? Click to expand... My 3.0L Duramax averages about 10 psi boost and EGTs of 950°F cruising down the interstate at 75MPH with no wind.

Click to expand... Diesels do that, but often it's done to lean out the mixture more. Any idea what the AFR is then? I'm guessing 25:1 or leaner? My old diesel ran with boost everywhere aswell, except when performing a regen, than it ran 0 boost just cruising
