Chally I wonder if those cells or not monitored. Does the emission tester know to look for them. Just a thought. I haven’t encountered any of this yet but I suspect I’m in for it once I swap the new to me 6.4 in my car.

I am pretty sure the P219A will prevent the fuel monitor from passing. I had a lot of DTC turned off in my original SC tune and the fuel monitor was always incomplete...even after several drive cycle attempts. It was not until I turned everything back on and preformed the drive cycle did everything complete. The code kicked in when I was doing 60 and holding throttle. Like I said, never had this issue when I installed the headers, only happened after the cam install.
