Here's an older post describing those lines, connections, and some of the implications of not having them attached.

On a good note, you HPOP looks great - ICP & IPR are right on target. Just need to find the low boost cause.

Looking at the data, the fuel should be rockin', but the air... in a word... sucks. This doesn't look like an EBPV issue or else the EBP value would skyrocket in relation to MAP (I see this on a regular basis). This looks like a wastegate issue, an exhaust leak, or a turbo issue. The turbine spins freely?

"There is something funny going on with the truck, yesterday and today I went to start it when it was cold and it ran really rough didn't sound well tried to drive it just a little bit down my street and it felt like it had absolutely no boost fit and very little pick up. On both days I took it back to my house let it sit for 10 minutes and then restarted it and it ran fine. This is what I felt right after I replaced the cac boots, but it is obviously something else besides the boots because it is doing it intermittently."
Doesn't this description sound like the EBPV being engaged? or perhaps the turbo not producing boost.
Now back to the most recent graph, the boost numbers look about 5 psi too low. Is the FIPW the result from the low boost or is the low boost the result from the FIPW?
What do you think about disconnecting the wastegate (plugging the red line onto one of the turbo clamps) close the opening where the green line enters the intake and disconnecting the EBPV........
