O2 Readiness with P0138/9 - O2 Sensor Slow Response checked
Hi! I'm trying to pass emissions and I have a downpipe that doesn't need the P0420 block anymore (it was messing with readiness). My tuner had also checked the O2 Sensor Slow Response box. I was wondering that too will affect readiness and if I need to uncheck it and reflash.

It likely will. The only suggestion we can give it to flash back to factory for emissions purposes.

Thank you for this advice.
