[ECM] 3884 - VCT Manual Control Switch: Disabled -- I'm guessing here but I would think you want manual control enabled.
tried no startQuote:

I see big MAP/IPC errors but what's even more concerning me is that the cam angles are changing. Does it have a physical VCT lockout installed?
yes physically lockedQuote:

That was my thought too, because of the difference in bank to bank. The installation procedure between 11-14 and 15+ is slightly different too.Quote:

after you locked out and enabled manual control did you degree and enter the cam angles? Also, is the IMRC locked out? The switch is enabled but the rest of it is set up as if it is locked out.
I'd suggest going to L&M engines and following their cam timing procedure. The ford one, while correct, is a little confusing.
could also be a really big vacuum leak.
I was trying to do a ghost cam and when my speed density was way off it did this.. what if you turn off cyl anticipation? I'm throwing guesses into the wind here
