99 Powerstroke missing and some codes

At my work there is an early 99 with 200,000 miles roughly. It recently developed a constant miss. I messed with it today suspecting the UVCH, tested it with an multimeter and got continuity on all 8 injectors. I brought along an Edge Insight to pull codes and got a P1247 for low turbo pressure and P0470 for the exhaust back pressure sensor. I have not checked it out yet to see if it is plugged, but I don't believe that is the problem. The miss sounds like it is only one cylinder. Looking for opinions on what could be wrong, injector? I don't have the capability to do a buzz test or contribution test, just looking for opinions before it's sent to Ford. Thanks!

you can try pulling one valve cover at a time, running it, and disconnecting ijectors one by one until you find which one is causing the miss. if it is an injector

the richest ones are not those who have the most, but those who need the least
