I installed FlashPro and uploaded a basic tune just changed timing slightly. Now I am getting P0400 "Exhaust Gas Flow" code and check engine light. What is the cause of this? All the boxes are checked for using EGR and doing EGR checks.

If you return to stock form the online menu does the error persist?
