I’m having an issue with rail pressure. While coasting it wants to climb to 14.5k while desired sits where it’s supposed to be. Also it doesn’t do it as bad after motor starts warming up. At operating temp it’ll only go to about 9.5k. As soon as the truck comes to a stop it’ll fall back in line with desired. And as soon as I hit the gas while coasting it falls back in line with desired. I honestly don’t know when it started doing it but it started popping the p0089 code a couple months ago and that’s when I started noticing it. It does in on any tune, it did it with the lb7 regulator and also now with the Lbz reg. And also before and after the SAC45’s which I just did. Lift pump pressure is 6-7 psi. Thanks for any insite!
