DPF deleted, EGR unplugged, no cel, have crawled under truck no SIMs or other mods on wiring. I bought this truck this way, have since bought a edge CTS insight to monitor the truck.

Question: how is the best way to find out what kind of tuner was used to keep this truck from throwing a code, I would like to get a tuner but I don't think the ECU has stock programing and have concerns about how to proceed.

I also intend to complete the exhaust, it now just has the delete pipe in place, I intend changing to a turbine back 4" with muffler, to Old for loud trucks or lots of Smoke.

Any Help would be appreciated, Ive tried several different searches and have came up blank.

Thanks, Brad

A pre US (delete capable) Smarty tuner will overwrite the delete tune in the ecm. I don't know if H&S or EFI can do this but I'm sure someone will chime in.
I don't know of a way to tell what tuner is currently loaded.
