car running weird?

Hey guys I am new to the ltx community and I need some help. Here is the deal I just recently put pacesetter off-road LT on my camaro ss along with an off-road y pipe(egr and air delete as well) and had the car tuned. On the way home from getting it tuned I got codes p0133 and p0153 for slow response of oxygen sensors. The sensors are brand new Ac Delcos. The car is also running very rich. Any ideas? Thanks!

could be the coating inside the headers burning off and just messing with your O2 readings, Id drive it around a little more and see if it improves.

Could it be anything tune related? The short term and long term trims are between -14 and -3
