General dtc question

[bad intentions]

I'm sorry if this has been covered before I did use the search for two days before I posted this.

But is it best for more PCM to perform a driving cycle and clear DTC codes on its own. Or should I delete them myself.

General o2 p1135 and 1153 my car has been tuned and these should be deleted but they still appeared, I have recently switched out to brand new o2s and waiting for the car to reset itself.

Thanks in advanced and my apologies if I upset anyone.

Those insufficient switching codes are very common with LT headers. Just set them to no error reported & uncheck the ses box.
