So I just had a 3 inch catless downpipe put on yesterday and had it retuned through trifecta with P0420 and P2096 erased in the tune file, it drove great for a couple of hours but then I did a WOT pull and it threw the above code. my question is if this is a common code to be kicked out from a catless system? Also am I able to go in and clear it and not have any problems?

Check your connections between the turbo and the downpipe and also the O2 sensor bung (primary O2 just behind the turbo), usually that code is tripped when you have high fuel trims at idle, but then the fuel trims look good while cruising.
