Default Can a PO1133 code be 'written out'??

Can a tuner, or anyone with; EFI Live, LS1 Edit, or a Tech 2 'write out' a PO 1133 code PERMANANTLY, or will this leave a "ghost" which the state emissions ***** can find/see during the OBD 2 plug in inspection???

This should be an insufficient switching of an 02 sensor. Did you get the code after deleting Cats? Have you tried simulators at all? We need more information.

You can definitely eliminate the code from ever being seen with hp tuners.

This has been "tuned out" on my car along with 1153 which would be bank 2 I believe? As far as I know it is permanent. Just out of curiosity, are you only getting the 1133 code, or are you also getting the corresponding code on the opposite bank (1153)?
