Perhaps i'm mislabeling the title of this thread but I recently installed (or half installed as the videos will show with my gauge pod still not mounted) both a HPOP and Fuel pressure gauge and am looking for feedback on how healthy the read-outs are.

I've noticed a little bit of a lag in power with my truck, and rather than grapple with the fact that it currently has 305,000 miles on it and everything is simply starting to wear out, i'm looking to see where some small troublesome issues may be. I put it up on a dyno and got 250 HP and 540 ft/lbs so I was rather disappointed. I believe stock trucks are more in the 300 HP range and i've got a few upgrades (see sig)
I've read that the injectors like to see 70 PSI of fuel pressure and 3,000 PSI of oil pressure.
Currently, when I get on it the highest oil pressure I've seen is 2,400. Cruising around town it fluctuates between 1,000 and 2,000 PSI...and when I say fluctuate I mean the needle is constantly sweeping all over the place. I know the oil pressure is RPM based but not sure if its supposed to keep a more consistent pressure. I will say I installed the high-flow ports dieselorings.com sells on my stock HPOP. Not sure how much of an issue those may be causing.
At idle and regular acceleration my fuel pressure is pretty steady, never really dipping below 60 PSI. However when I get on it I've seen it go as low as 45 PSI. At KOEO my fuel pump whines as it builds up pressure so I'm wondering if its one of those worn out parts. I currently don't have any modifications to the fuel system.
The only other issue I think I may have is a boost leak. I run 100% biodiesel in the summer so with it being such a clean fuel I never get black smoke. However today I put regular diesel in, ran it hard a couple times and got some black smoke. At cruising speed I'm only around 2-4 PSI, normal acceleration around 8-10 PSI and it'll get a little over 20 PSI when I get on it. I remember it getting closer to 30 PSI under hard acceleration before the MAP sensor de-fueled.
