Swapped out the 5.9 rail to the 6.7 rail and changed nozzles from 80% to 170%.
My idle rail pressure now is almost 11k. I am using the 5.9 rail pressure sensor

I assume it idles and drives a bit funny? or no

One would think.

OP the rail pressure scaling will have to be updated to match the scale of the 6.7 RP sensor.

He's using the 5.9 sensor on a 6.7 rail.

It's due to the different nozzles. Sometimes big nozzles will actually flow a bit less at idle. It's pushing further into the map to maintain idle is what it seems to me. Do you have a v2?
