HPP3 throwing a code - questions

![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
I 've the HPP3 on my car for about 8k miles. I got an SES the other day. Went to a dealer, w/ programming still on, and they said it was a cat. convt. efficiency problem. I put the stock tuning back on this morning (in prep. for taking it back to dealer today) and the SES went off! Does the HPP3 cause the motor to run lean, thus causing my rear 02's to read wrong?
I did a search, and no one else had this specific problem. Also, I've got LT's and true duals waiting in the garage. With 02 sims, can I put the HPP3 tuning back on? Exhaust is stock for now. Thanks for any advice/input in advance.
