is running exhaust brake all the time ok?
In my new F350 with the 6.7 I like to run the exhaust brake even when not towing. I find it helps in stop and go traffic and requires me to use less brakes. But is it OK to run it all the time? I mean...

The only thing I've noticed is that the EGT's are higher at idle with the engine brake on than they are with the brake off. I usually allow the EGT to hit 300° or below, before I shut the engine down, but with the engine brake on it won't go below about 350°.
That's a bit strange. Not that EGTs are higher with exh brake activated. That is expected and a good engine warmup technique in the winter.
But IMO, these fancy new fangled (LOL) computerated dual function vvt's should not engage at idle (aka warm up mode) once the engine is near or at operating temperature.
Even the old BD inline exhaust brake I installed on our 07 would not activate after the coolant temp was above 160 F IIRC. It was also semi-integrated into the truck's ECM. I only know this as I plumbed an air line off the compressor for airing up my air-bags and bike tires etc while camping and it would only engage if the engine was cold or not fully up to temperature, shutting off once it reached a certain temp.
Newer Ram with OEM turbo does the same.
