P 1211 Code
Lately i have been throwing the p1211 code and it says injector pressure above/below desired level. I have a 17* pump and it never did this when i first put it in. Is there a way to measure the pressure the pump puts out or could there be any other thing going wrong. I can even throw this code in my economy tune?? The truck really dies out top end.

1211 = If set during normal engine operation, indicates engine is operating in open loop control and injection control pressure is above or below desired pressure.
If set during KOER test, indicates ICP system failed step test and could not maintain commanded pressure
Here's the test:
