So I have my 2013 SS with Headers, Muffler Delete, And Dyno tuned, and about 2 months after getting the Dyno tune done at a shop my Check Engine Light came on.... So we tried this code reader and the codes that showed up were -
P2270
P2272
Which after a quick google search appear to both be directly related to the o2 sensors. So we reset the codes and now my car almost feels like it is running like it did before the tune, or maybe its just because something is wrong with the o2 sensors, or maybe its just all in my head...??
1) Will resetting CEL codes restore the factory tune?
2) Anybody know what exactly these codes mean (P2270, P2272)?

Resetting codes will not restore your PCM to stock
These codes mean O2 signal stuck lean Bank 1 sensor 2, Bank 2 sensor 2
I suggest you revisit your tuner.
