New code problem...help?

2013 Kenworth w900 isx15...de-mandated few years ago. New turbo at that time. About 9 months after I bought it...I had to do a rebuild. Did out of frame full rebuild because of structure leaks. Replaced all injectors, CAC, rad, did update to fuel pump, and more. Truck has run pretty great since then (about 200,000KM). Pulling B train oil tankers.
Here's my new problem.
Getting a Check Engine light and code on the Road Relay screen. It happens when on an incline under load and when I level off...it goes away.
The pyro will go up to 1100...turbo maxes at 30psi and I get this code:
* PID 157 ENGINE CONTROLLER INJ METERING RAIL PRESSURE RESERVED
I changed fuel/water filter and engine fuel filter. Also I changed the exhaust gas pressure sensor because that had thrown a code a few times before this code ever started. Once this new code showed up...the gas sensor code stopped but I changed it hoping that was the culprit. But no luck
Anybody ever see this issue??

* You need to find out what the actual cummins fault code is using Insite. Those road-relays are great but sometimes the code descriptions can be deceiving or out of date.

* If it was not done by Unilevers (or someone else highly recommended on this forum), then you need to have the programming checked out/inspected for safety and stability.

* 1100 on EGT's sounds a bit high, and only getting 30 lbs boost max sounds a bit low.
