Gearhead tune obd code P2272

[SoCalSHO]

Just had my turbos rebuilt with the CR Performance upgraded CHRA. Put around 50 miles on the car, the "check engine light" came on (solid, not flashing). I checked the code (P2272) and it came back to an O2 sensor. As far as i know, the sensors were not touched during install. Is this a common problem with the GH tune, or did it just happen to pop up?

The sensors need to be replaced with some degree of regularity.

That said, not sure exactly why the code you cited popped up, but I do know that I alone am on my 3rd set of sensors, @ 81k.

I get the same code on my truck occasionally, due to a small exhaust leak sucking air in.

bank 2 sensor 2 lean could mean either of the above - the oxy sensor is bad or there is a small leak in/around the cat.

Thanks all. New sensors it is. But I have a quick road trip first, so first thing Monday.
