Ok, same thing is still happening but now I am getting alot of backfiring from the exhaust..

I found out a few days ago 2 injector's went south, I replaced them, I did the boost leak down test, found out I have a few cracked lines I replaced those today, the only one I have yet to replace is the main Intake pipe.. it leaks a little.. But I am still having the same issue..

Also, my manual boost controller, is completely CLOSED, and I am getting 15+ PSI when I can boost
When its cold the car boosts normally no problem's, once it warms up, it has no power on boost and now is beginning to backfire. What am I missing here?

You sure you got your coil pack connectors back in the right places and that they're all firing?

There isnt a miss in the car what so ever. It rides and drives smooth. now I do know my coolant temp sensor is bad, I am replacing it today. But that wouldn't cause the issue I am having would it ?

Also I know the last boost leak I have is the top right intake hose. what can I use to replace that with? cause I can not find a stock one anywhere, and I do not have the cash for the hard piping kit

But once in boost it bogs down likw its not getting fuel

probably because when the car is cold it runs richer... and a boost leak would def cause problems like that, plus the temp sensor. fix the known problems first or you will never get to the bottom issue.
