Don't get discouraged, you can lick this. You've checked many things and followed a few false leads so start with basics.
You just changed turbo, correct? Ran fine prior? That was the last change made prior to issues showing up? Still have the old turbos? If so swap them on and see if the problem goes away. If so, swap one back on and test, then the other. Backtrack through the changes, start with basics and test. If it ran fine before and you made changes then something caused this. A bad turbo could cause this as one turbo would be trying to feed both sides, easiest way to check that at this point is to swap the old ones back on IMO

Thanks for the kind words and good advice. Yes the car right perfect before the turbo swap. I'm thinking this will be my next step.

Unfortunately I can't do that since the last flash and stock flash are for stock injectors and the car now has 72lbs injectors. My tuner has been great though and working with me to solve the issue. He checked a log and the car is commanding more boost than it is making so it shouldn't be the tune. Thanks for trying to help out though!!

I did check the cool side of the turbos when I had the intake tubes off and they seemed to spin fine.

You'll almost certainly figure it out while pulling the old turbos. Heck you could even do them one at a time just to check. You may see something obvious as soon as you pull them too. It'll work out and you'll have learned a bunch I bet! How hard were the injectors to do - that's high on my list too!

OK so after reading this I went out to take a look and this is what the dash reads while doing to boost leak test.
At under 5psi (0.2bar) the dash reads 0.1 to 0.2 bar
At 5psi (0.3bar) the dash reads 0.3 bar
At 10psi (0.7bar) the dash reads 0.3 bar
At 20psi (1.4bar) the dash reads 0.3 bar
At 30psi (2bar) the dash reads 0.3 bar
No idea what this means? Can the dash default to a max of 0.3bar when the car is not on?

Markski is supposed to be an expert on boost leaks and testing, send him a PM maybe...

Swapping in known good turbos if you're confident in your leak test is your next best test if you're really sure there's no leak. If boost returns you're going to know it's a turbo and nail the issue down quickly.

Well, I spoke to the company that modified the turbos to 20G billets. They said they noted the turbine housing was machined and informed the person I bought them from that they believe the turbos would have issues.
There are a couple of other pieces of info that I have that I will not make public at the moment because I have contacted the guy I bought the turbos off of. He was really good to deal with when buying the Turbos and I think is a genuine good guy so I think he will make things right.
The plan is to swap the stock turbos back on this weekend.
Man, so much time and money wasted I don't even want to think about it.

I spoke to the seller by email and as I suspected he is being good about this. He is still convinced the turbos are fine (and I hope he is right) but he agreed to refund me if I send them back and they are in the same ocndition as when I got them.
So this weekend I will swap back my stock turbos which will tell me for sure if the problem is with the turbos I bought. If it is I will send them back for the refund. If the problem is not with the turbos I will obviously keep them.

Missed this before...but .3bar is limp mode? This means you have another issue? Did you try a "reset"? Disconnect your battery for a few seconds, reconnect and go drive it?

OK, but .3 bar is only about 4 or 5psi? You should be pressure testing with at least 30psi?
