Just a side note, had a buddy who drove a 2008 F250(same system) and he lived 10 miles from our job sight, yep, you guessed it, his would go into regen, never have enough time to complete, restart, going and coming and would get 7 mpg for a week, until he made time to take it out on the highway and run it down the road for 30 or 40 miles to get a complete regen. Ain't technology grand. We run a lot of trucks that the pollution systems "have fallen off of" and have tunes applied. Haven't found the need on the new Chevy "yet" but will if I have any problems with or created by the pollution system.
