not sure where to ask or post (newbie) but here it is . 2008 f250 6.4 havig problems with truck quiting when going into " exhaust cleaning mode ' then it says "stop safely now " then when u stop it quits . the only way to get it going again is check and clear codes with (hypertech tuner) then it will start and go again for various lengths of time , some times 1-3 days . codes are p242d ,p200e , p242e ,and p1000 any ideas? does the same with stock tuning or modified tuning

mine did that with hypertech too.
switched to H&S and dpf delete tuning and never looked back.
i had two trucks do the same thing with Hypertech

Sounds like your running tunes with the dpf still on. Idk about hypertech but I would go ahead and delete the dpf and maybe switch the tuner if it still gives you problems. You can ask your local advanced oriely or auto zone what the codes are. Mine did the same thing when I unplugged the dpf so just delete it and be done.

You can't just unplug your DPF... You have to remove it and tune for a DPF delete. Otherwise you are just clogging the DPF and never cleaning it out.
