6.4 EGT temp before shut down??

[Motorboy8769]

With my6.0 I used to idle until 300 deg should I wait until 300 with the 6.4 or is it safer to shut her down before that

I always shut down at 300 F or 3 mins on my turbo timer, whichever comes first.

I shut mine off between 350-400. Always have. No problems with stock turbos or my Elite setup. Truck has 140,000 miles on it.

You are safe shutting down at 400. I let mine get between 350-400 depending on how hard Ive been running the truck. If I waited until it got to 300 I would have to sit for awhile.

Mine gets cool really quick. It gets to 300 and the high 200's fairly easy and that's when I shut it down.

Same here.

Mine cools to 300 quickly also except during 100+ degree days after a hard run or pull.

I previously had a deleted '08 Cummins that would take quite a while to cool to 300.

I feel like my 5" exhaust and 4" DP help get the hot exhaust out of the turbos quickly.
