My first trip up in the Idaho mountains (-15 degrees), my 07 Cummings gell'd up on me even after adding 16oz of the white bottle (Drews brew). To make a long story short, after changing filters and so on my EVIC messaged that my exhaust filter is at 100%. And it is also saying the vehicle is in power save mode.

The dealer said to run the truck at high speeds to burn out the soot and that the truck should go into a mode that dumps more fuel in to make the temp go up to burn the soot. Well in the power save mode I can't get over 65 mph to do anything.

So any information on how to fix this whould be greatly appriciated. My personal email is rockvalleyroosters@gmail.com as I don't check the forum regularly.

Thanks

Danny
