Could it be one of the below? There aren't many codes that stipulate Catalyst in them.

P0420 Catalyst System Efficiency below Limit - Bank No 1.
P0421 Catalyst System Efficiency below Limit - Bank No 1.
P0430 Catalyst System Efficiency below Limit - Bank No 2.
P0431 Catalyst System Efficiency below Limit - Bank No 2.

yeah thats not the number i got but it was exactly that word for word and im pretty sure it was bank 2. it hasnt happend again. and i switched back to a different tune that had been working for a while without any major issues.
