Agree. A simple $99 OBDLink MX+ with their software that comes with it will easily show the temps plus a number of other PIDs. The screen shot below is when the truck was shut down but will grab one when running as the temps can easily reach 800 to 900 degrees and even higher during regen. Updated pics…center pic is at 70 mph…far right pic is after 2:00 minute cool down.If you're a techie kind of person buy yourself a gauge or use an OBDII reader and Smartphone and monitor your EGT's. It will become quite obvious to you that it would be wise to let it cool down a bit rather than shut it off at 800° after towing. Everything gets real hot from the Turbo inlet through the emission system. If you turn it off in the middle of a regen your DPF can be over 1200°F.
