Truck has been running terrible. Long starts when cold (below 50) where it seems like some of the injectors aren't firing for a bit (all glow plugs and relay are new and I've double checked they all work with a meter). Finally got around to getting the torque app and a Bluetooth adapter for my truck. This is the info I saw today.

Cold Idle right after first start (70 degrees outside)
15.1% DC
730-750 psi

Warm idle with EOT up to 200
7.7% DC
480 PSI

Street tune
92.8% DC
1524 PSI

Stock tune
50% DC (this is the highest I saw, it kept climbing slowly
2200 PSI (and slowly dropping)

I'm going to be upgrading to single shots here pretty soon, but I'm thinking there's no way this thing will keep up so I need to fix the issue.
Is this definitely the hpop that needs to be replaced or is there anything else I can check to make sure the rest of the hpo system is up to snuff? I have no external leaks at all but my truck does drink about a gallon of oil every 5k (turbo). No oil in the coolant and I just changed the oil 2 days ago and there wasn't anything in the oil.

Your idle psi and DC look in check.

But that 1500 PSI at 90% DC is baaaaaad. LOL

If that's at WOT, I'd say you need a pump. But tuning could play a factor in why that DC is so high. Who's tunes?
