Have you driven the truck at all since returning to stock? I've heard/read, that you have to drive it for a good bit after returning it back to stock, or download the DPF tunes on the Quad, then do a manual regen, see if that takes care of it. It's because the truck now recognizes it hasn't done a regen in a while, and it wants to make up for lost time!:rolleyes: Chris

Why would you return it to smog... I say sleeve the DPF and smog test it without the return stuff. It's a job...

Straight Pipe it so it looks installed put 5 in. exhaust system on all the way with or not a muffler for emissions. Use EFI or PPE to delete codes so no lites on dash and it'll pass the smog test but won't be wasting fuel. Look at the DPF delete kits and imagine this in the system you will get a better idea if you still don't get a clear picture from this fast clip.
