What did you do to fix yours?

New cat y pipe installed for free from GM. THEY HAVE TO WARRANTY EMISSIONS FOR 80,000 MILES.

That CAT did get a plastic bag stuck to it a while back, would that do it?

The bag won't do that, but focking with the tune will.
Also, if the dlr sees the converter has been overheated, and scans the pcm, and finds a tune.. U R focked again.

As for the other dash.. Won't work if your truck has been to the dlr w/ miles higher than the Escalade dash has on it.. Focked again!
