P0087 & P2047 OBD II Codes after CEL and loss of power on 07 E320 Bluetec

Just 3 days ago, my car threw a CEL while driving. Power seemed reduced, but I was in low speed traffic and just wanted to get home so I didn't test it. Started it up and drove it a few times, and it drove fine and the CEL light went away. Today I was driving about 50MPH when the light came on again. This time, because I was merging onto a highway, I felt an immediate impact on performance. The car almost didn't want to Rev higher than 2K, even with flooring it. I could manually downshift and get it above 2K, but didn't want to force it. I could still accelerate to 65, although very slowly (almost like it was now naturally aspirated, but with even less power compared to a 96E300D which I have and is NA).

Scanned it with Torque and a bluetooth OBDII scanner, and it came up with the following codes:

Some quick googling looks like it could be related to a fuel pump issue, but I haven't heard of too many of those with these engines.. Looking for some guidance.

Fuel pressure problem, ever changed your fuel filter?
Can your OBD scanner data log? If yes check your rail pressure.

You have a tuning box?

Fuel filter was changed around 30k ago. I'll check to see if I can get the logs. I do have a tuning box (diesel power Gen 2, boosts Turbo and increases injector duration...)

07 E320 Bluetec

Except an alternator and battery change in the second year, I've had no issues on my 07 Bluetec, however I've only done 30K miles since new. I have the KD-Box, nothing fancy.

I've turned it to basically off, I do have a module which can just bypass it, but it's not with me right now. I had been running the box for the last 7 months or so without issue.

Hey this box messes with the railpressure so just unplug it and try, had the same issue years ago.

turning off isn't getting out of the wiring
