Hot start and missing problems???

I'm new to the forum I've been looking to it for answers for quite some time though but now I'm having an issue with hot starts. Early in the morning it starts fine. Runs rough but starts fine. But it misses and cuts out bad. After it warms up it either will not , or it takes forever to start back and still has a pretty bad sputter through out the rpms. If you let it set for about 30 minutes it will start back fine. Still missing and sputtering though. Also when you really get in it it clears up until I start cruising again then starts with the missing and sputtering again. Any answers would be greatly appreciated. Thank you. The truck is an 03 6.0 new turbo injectors egr delete arp studs sct with custom tunes 190 horse injectors and edge juice with attitude.

Maybe the High Pressure rails (The ones over the injectors) have a leak, have you made the air leak test?, what's your HPOP pressure?

Ok, do you know where is the icp located? its over the passenger side, next to the oil fill pipe.

You should take out the valve covers, both sides.
Open the switch but no start.
Fit a quick connect coupling to the ICP thread and let the compressed air flow trough the system, you are going to hear the air leaking and you can put oil all over the injectors and the HPOP piping to reveal the bubbles of the air leaking.

If you need further help, inbox me

Just to update a little I drained 2 quarts of oil out today to make room for some hot shot secret and noticed the oil smells a lot like fuel and it has been black smoking a lot more than it should. Even if I'm barely on the throttle is hazes out and if I have to pull a hill it pours out
