Only P1094, EGT 50 Deg Higher and mileage 2 lower

Well, the truck is acting a little strange. I am seeing lower mileage (13-14 vs. 15-16 for same average speed) The EGTs have risen by about 50 degrees and I set a P1094 code. There was no P1093 that everyone talkes about for a FPR or CP3. I have a lift pump running around 2 psi but it seems like the pressure is much more jumpy than I remember from the last time I checked it. The Pred fuel pressure request vs. actual is close but seems jumpy as well. Thoughts guys?

I have been doing a lot of reading on the FPR and CP3. I am thinking of throwing a FPR at it since I've had lopey idle forever. I run 3 oz of Total Power in every tank so the lope is minimal. Another thing that I have seen is my remote start won't stay running. It never has a problem when I use the key and it doesn't do it every time. I checked my lift pum and am running around 2 PSI. This and the loss of fuel mileage is getting annoying to be honest. I should be able to get this thing back to at least the 15 mpg I used to average in town in Dallas since I now drive almost total highway to and from work instead of stop n go. I only have 114k on it and the injectors are all less than 5.

Update: Had a guy ride home from work so I had him watch fuel pressure on my Predator. He said it was normally 5-7 MPa above request but sometimes was lower by the same amount. I stood on it and it did command the 160 MPa limit and was at 158 something so it looks like my CP3 is ok. So my question is 5-7 MPa off too much? It sounds like it to me and considering someone else said they were having the same issues (lopey idle, loss of MPGs) that I am and it all went away with a new FPR I'm thinking that's this weekends project. Opinions?

FPR Replacement Required So......

Just for S&Gs I got a quote from the Steeler to replace the FPR or the CP3. They want $1243 plus tax and "shop supplies" for the FPR and $1404 plus T&SS for the CP3. So, I ordered one from Merchant this morning to do it myself on Saturday. Even with express shiping I save $220 on the FPR part alone. They told the wife they needed to remove the intake manifold to do either and that's why the labor was the same for both. WTF? Any good techs want to relocate to the Texas/Mexico boarder? You could make a killing.

Just finished replacing my FPR. That was a pain in the . So far it looks good but the EGT are about the same but load is lower.
