Tune won't help if the air-fuel ratio sensors are already switching slowly, basically you need new sensors and then run the stock tune while it's getting tested, unless there's a way to temporarily revive air-fuel ratio sensors, you could just get a new set of air fuel ratio sensors, swap them in for testing then take them back out and put the bad ones in for driving until you need to test again

Put the tune back to stock and drive it so the sensors reset

He did.

I heard something about an "Anti spark plug fouler" screwed onto the O2 sensor then that screwed into the cat would trick the system.
Not sure if that's works or not.
