Did this happen suddenly?
Check ALL connections again, i.e., Turbo, IC, up pipe, vacuum hoses (blown off, split, etc)

check to see if you blew off one of the turbo tubes of split one of the rubber connectors.

My foot was in it, I herd the air, then I creeped it home!!

Your engine is getting unmetered air. This is why you have trouble keeping it idling. You are getting no boost because it's bleeding off. As stated above, you have torn, popped, ruptured, split ect. ect. either a hose, pipe, or intercooler. Pull, push, twist everything from the turbo to TB. Check your clamps. Report back. HTH, Brian

 

[runemdownwilly]

Just checked the hoses pipes and clamps they seem fine. Is it a cracked intercooler does that happen??? DOES ESP WARRENTY THERE FRONT MOUNT LOL...

 

[Fuelie600]

It's not likely, but I wouldn't look past it. You should also check your intake, TB, plenum, and vacume block gaskets. Look at you wastegate, boost solenoid, and other vacume hoses. You have a leak somewhere. If you heard a loud hissing, it has to be a substantial leak. I still think it's in the turbo to intake plumbing. Good luck, Brian

Hay Brian, Thanks for the insight. The weld on the intercooler was split all the way up on the back side I couldn't see it till I got under it

 

[Fuelie600]

Sorry to hear about the IC, but I'm glad you found your problem. Brian
