Got my dp tuner in and I got some codes heres what they are

P0278 Cylinder 6 Contribution/Balance Fault
P1670 EF Feedback Signal Not Detected

It was cyl 5 fault and now I get cyl 6. I understand that the ef feedback code is from the idm to the pcm. I am guessing maybe when I put the chip in there is one of the connectors on the pcm not getting a good connection? Should I remove the chip and try reinstalling? Any help would be appreciated.

How well did you clean the terminals?

Did the truck run?

You had the truck off when you unplugged the pcm right?

Just runnin through the basics.
