jdfcc I have moved your thread to the 6.2/6.5 section to get more views to get your issue resolved a little quicker.
The IP is out of spec and will have the corresponding trouble code.
First you will need to rotate the IP towards drivers side fender about 3mm,clear codes and then do relearn procedure with coolant 170f+ as often as needed to get in spec.
You are not looking to get TDCO to be 0,it should be -.25 to -.75 for stock spec or -1.5 to -1.94 for performance spec.
