Yes it needs to be tune to stop the computer from throwing codes and enabling the CAT diag tests on you.

There is a COT (cat over temp) that you need to disable under the Engine > Fuel > CAT/DFCO tab.

Under Engine Diag > Exhaust there is a Post o2 sensor test and a cat converter test itself that you need to disable. Then you need to disable all Bank 1 sensor 2 and Bank 2 sensor 2 codes. Change them all from 2 MIL on Second Error to 3 No error reported.
