The cam, lifters and valley plate where all replaced and the truck ran, but when it shifted from v8 to v4 I would have no power even with my foot on the gas. So my thought was that it was sending unburnt fuel through and that’s what damaged my cat. What are your thoughts? The reason is I need to make the shop pay for a new cat for there mistake of not doing the tune.

The reason why I'm asking this is that they released my truck to me thinking that all of the delete was complete but it wasn't after a 100 miles I was throwing cat codes and the engine was noticeably shifting at a coast.

I recently had my 2017 Silverado 5.3 engine rebuilt with a DOD delete kit. The shop did the physical delete, but did not complete the tune of DOD delete. My question is would that cause damage to my catalytic converter if I drove it?
