No matter whats wrong, you need to remove the cats.
Are you using an octane booster? If so, I would replace the front widebands and also remove the cats. Then you'll likely be fine. Dont bother yourself with LTFTs. They can get skewed and the shorties will offset them in real time. I see...
Contrary to what the (stupid) public thinks, its the driveline that needs to be broken-in or "run-in". The engine break in would need to be hard and fast. In order to get the best compression you can from this engine, you need heavy engine load to increase cylinder pressures. That will seat...
The lost comms DTC is from flashing the tune. Should clear with a code scanner. I see these every day after flashing tunes. First thing we do after a flash it start the car, then immediately clear the DTCs to clear out that and a few others that are normal.
The metal casing mushrooms when they are tq'd on too hard. Then they expand and no longer fit the correct size. The metal core is still good, but they can sheer off the outside then good luck getting them off. The jeep wrangler has those that do the same if they are pounded back on with an...
Unless you just tipped out of the throttle, this is a problem. You should be in closed loop fueling unless you go into tip out DFCO for a few seconds. If this was at WOT during a pull, then you might have issues with a wideband.
Your fuel trims are lopsided. Driver's side is adding more than...
Safe bet. Even better splash some e85 in there as well and raise that up to e20 or e30. Then you will get the full potential of the stock calibration with no KR.

Lots of the issues I’ve seen were from transport and at the dealer. My DH was riddled with dings and scratches from sitting in the showroom for months. Dealer messed up fixing a few of the issues on that blue ember paint and I walked away from the deal after the fact.
