The never ending story..... On my way home yesterday, ofcouse you know i had to do some more testing. I got on it a few times then te next thing you know i'm loosing boost again. When i get home i look under the truck to find out were the exhaust leak is now. I blew the gasket out on the waste gate. 
Luckly i had some gasket material and was able to make another. So all is good

I drew the Tial 38mm flange pattern in CAD and had our fab shop laser out a few gaskets out of .060 al. I then heated it up with a torch to soften it. It's re-usable, cheap and I've had no leaks with it.

Update!!!
After install the GT67 I did a cam (GT2-3) swap two weekends ago. The pass two weeks I've been logging and tuning when i have time. Got it running real strong @5psi. It's making over 520lbs of torq on HP tuner. Thats about 70lbs more than the T60 did @ 8psi. I haven't tried 8psi yet, I was going to tune for it with open exhaust for when i go to the track. Now for the bad news. 
Yesterday i noticed oil on the tailgate of my truck. So i look under my truck and there was oil dripping from the exhaust housing of the turbo. I checked the oil pump and it's working fine. So i Put the T60 back on and took it out for a few WOT runs and no leaks. I may just keep the T60 on. I kind of like the instant boost 
and smoking the tires down.
