Exclamation Help!-P2289 Injector Control Pressure Too High - Engine Off

Ok so driving home today I noticed my truck was running weird, it wouldnt go over 12,000 psi of fuel rail pressure and was making 45+ psi of boost on my 210 tune when before it made 32 tops. This is coupled with the squeaking issue Ive been having since my HGs were done which I am pretty sure was a boost leak

The truck had a lot of power down low more than before but when I went over 3/4 throttle the truck completely defueled and bucked real bad until I let off the gas. EGTs were also about 100 degrees cooler than normal. So I scanned codes and that is what came up. there was also weird kock/tick coming from the engine. The squeaking was also a lot less but the idle was at a lower RPM than usual

So I cleared the code and the idle immediately changed back to normal. I drove it and it seemed to be normal but the squeaking was much louder.

Also I noticed that at 3/4 throttle I was now making 25-26000 PSI of fuel rail pressure.

I have no clue what the hell is going on. Anyone have any ideas?

Is that a different parameter I can monitor on the dashdaq besides just the regular fuel rail pressure? Sorry that might be a really dump question. lol

KOEO FRP should be 0, or thereabouts. (0PSI/0.49v KOEO, according to the PC/ED manual) I have seen it ~8psi or so on some trucks.

Sounds like you might have an FRP sensor issue. PM me your VIN and the DTC and I will have a looksee if I can suggest you any info.
