T660 emissions stop switch?

[Chamberpains]

Just got done working with Mommaburt on this truck. And the verdict is....... We surprisingly found the man himselfs very early release of MM. This explains the smooth running and clean intake. Someone over this way found your work and put it to use. I would take a stab that it may have been Gearheads shop but It wasn't perfect. It was definitely way better than the nightmares I read on here. Where it wasn't perfect was actually less of everything. Mommaburt said someone actually cut everything back. It was gutless. Which, if I'm gonna choose, im glad it wasn't all cranked up or some stupid ego stroking garbage.

I got lucky with this one. The guy I bought it off of told me it wasn't demandated. But I found the empty DPF and today I found the sneaky stainless blocking plate in the cooler. Also whoever did the programming did a fairly good job of covering their tracks. There was no record in Insite of the programming download. It was still tagged with everything identifying it from the original big fleet it came from and the upgraded original cal number. It even had some old inactive emissions related codes so without out knowing exactly what to look for with Insite or CT or actually cracking pipes apart the average person wouldn't have been able to tell it was ever altered.
