My 6.7L with H&S DPF delete is basically undriveable and continues to be stuck in regen even after having the batteries unhooked overnight, the edge set on clear CELs, and with the new fooler boxes installed. Has anybody else had a similar problem? Would taking the truck to the dealer to have the computer reset solve the problem? The truck is a 2007 purchased in early 2008. Could my computer be different enough from a 2008 that the H&S fooler boxes won't work? I am in a real mess with a brand new truck that won't run and no local diesel performance shop to take it to. Any help would be greatly appreciated.
