Need Help. P0365, P0390 2013 XLT

I recently replaced timing chains, tensioners, phasers, camshafts, lash adjusters and followers after experiencing a rough running event with a P0025 code. After reassembly I keep getting P0390 and P0365 and the engine will not make power. Ive pulled the valve covers and front cover 3 times to make sure that it is timed correctly. I've replaced both cam sensors, and checked continuity from the sensors to the ecm connectors, everything checks out, but these codes always come back. Any help would be greatly appreciated.

I gave up on it for the time being. I did bring it to the dealership, but they started at the beginning, doing all the things I had done. I stopped them when they wanted $1300 for an ecu that may or may not have fixed the issue because that's what the book said to do as the next step. I know for a fact that it's not the sensors or wiring and just for fun, I replaced the ecu as well, also to no avail. I just pulled it back into the shop to start digging back into it. I plan on taking a closer look at the phasers. They're new, but I did buy them from amazon (seller that FordMakuLoco suggested), so there is a possibility that they are defective.

What about you, did you figure anything out?
