Losing my mind with P2096/P2098 errors after a tune

These codes are for downstream/secondary oxygen sensors that are responsible for monitoring a proper functioning catalytic converters. You have HFC and those usually will throw codes periodically. Some tuners will disable the monitoring of the cat but then if you need emissions inspection, it would not pass. You can try extended bungs on the sensors. Some had a good luck with those or invest cheap obd scanner and just clear the codes when needed.

So nothing to worry about with the car itself (leaks, wrong air/fuel ratio)?

I'll try the scanner. I hear you need to drive ~20-50 miles after clearing the codes or they cannot perform the inspection, so I'll look into that. Appreciate it

Actually those codes can be due to exhaust leaks around the cat. Often the aftermarket HFC uses the triangular flat style gaskets which will almost always leak. I would suggest checking for exhaust leaks between the header and the cat - the past 2 people who came to me with those codes had stock cats that someone had re-installed and they didn't use oem crush ring gaskets and leaks developed causing the codes.

Send me a message if you would like me to review the logs from the tune and help you narrow down the problem. Leaving this issue will result in the ruined cats because the ecu will add extra fuel to light-off the cat to reduce emissions. I'd suggest digging in and solving the problem or at least gaining confidence in the cause.

I recommend this advice 100%. I'm tuned by Eugene with high flow cats, been working with him for years, and never had this issue.
