I just did a few checks on mine for comparison. Starting with a cold car (parked overnight)...after a few minutes of idling the crossover pipe is scorching hot, the crossover to wastegate piece is fairly hot but not too bad, but the dump pipe is as cold as ever. I went for a drive and used a little boost and checked again. Now the dump pipe is hot, but I can still put my hand on it. It's nowhere near as hot as the forward sections of the exhaust.
How does that compare to yours? If your wastegate dump pipe is hot to the touch from a few minutes of idling (starting with a cold car obviously) then your wastegate must be stuck open.

Your symptoms sound identical to when my boost was zero. It would pull great vacuum, but, no boost pressure. Check the balance of your turbo, as well as for play in the shaft. It could be the turbo on it's way out.
You have to have a GIGANTIC leak in your intake/vacuum system to create a zero boost situation.

I have not. I didn't get the new wastegate yet. I should get it tomorrow, then I need to get some time to swap it out as I can't do it in my small 1 car garage. I will be taking it to DIY to swap it out.

if your wastegate is not stuck open you might want to consider pulling the turbo out, your situation sounds very similar to what happened to doabarrelrrol

0 boost usually means your turbo is finished.
If its the wastegate, you'll still see boost. Even if it's stuck open. even if it's 1-2 psi.
the CV would do the same. You'll see some boost. not much though.
Or the Xover is collapsed and the wastegate is open all at once. That would be 0 boost.

If the turbo was toast would it go from one day boosting 10-11 PSI no problem to the car sits overnight in the morning it makes 0 boost? That just doesn't seem possible. I never heard any weird noise or anything. Also the turbo spins fine from the intake side where the J Boot connects.

The wastegate and the wastegate valve are no longer connected...BTDT.
