Okay I have an update when I first had the problem I went to full force diesel and told them so they sent me a new set of tunes now on the first set of tunes I was getting 13 pounds of boost with the second set of tunes I was only getting 5.9 pounds of boost so this morning I told my self maybe I've had a problem with the tunes this hole time so I went out downloaded the old tune on it and boom went back to 13 pounds of boost now that's not high by no mean but I felt like I had finally found some of the problem and at least my truck could jump out of its own way. Now I'm running the hydra chip and I was looking at going strait to power hunger performance and getting there tunes where else would you go to get tunes for the hydra

The stock PHP tunes are not dialed for single-shot injectors - particularly with 80% nozzles. You should get so much fuel and have such a touchy throttle that it's a neck bender with contrails. Now that you're getting smoke - is the smoke above 2K RPM, below, or both?
We need to see that IPR and ICP, but a log of the data would be much better.

Did you get all the clamps on snug when you put it all back together? Don't overtighten on the plenums unless you have reinforced them with upgraded ones, but sounds like you may have loose fitting(s) somewhere. If you're certain everything is snug, you can make a boost leak detector and blow shop air into the system, then spray simple green from a spray bottle on the common areas for boost to leak to find where you may be losing some.

I've cleaned the pipe twice now and still no luck so now I'm making a boost leak detector just to be 100 percent sure but I still can get anyone to explain why on one tune I can get 13 pounds of boost and on a 140 tune I get 8
