I think once you get the EWG and Fuel Wires set up send some logs to Terry and he will help you fine tune.

p2096 is a fuel mix code. So you have a vacuum leak, o2 sensor issue, or are running too much E85.

Also possible you attached a fuel wire wrong.

Good that is an expected code when you remove emissions equipment.

So what can we do about the p0420??

Get an 02 sensor defouler. It's a mini cat that goes over your O2 sensor. Or get a tune that turns it off. A piggyback can't do that. Or just get some black tape and your light is gone
