I have about 400 miles on the new wix fuel filter. Lift pump is in the future. Quinton. I may hit you up this weekend or next week if it's not better tomorrow. I sure appreciate all the help guys.
New Turbo and still NO boost. HELP!!!

Cold air intake being ordered today and maybe Y bridge and lift pump next week. I've already thrown $12k in this truck since I've bought it two months ago. Sickening.
That turbo would run fine with stock tuning if the truck is mechanically sound, just not optimized for best performance.
I recommend pressure testing the complete high pressure side system on the truck. Intercooler, boost tubes, Y bridge, and have the turbo inspected if that comes back negative.
I'm guessing like everyone has already mentioned, you have a boost leak.
Tuning can do cool things, but cannot fix mechanical issues with a truck no matter how many versions are made and sent.

This^^^ take the wix off throw as far as possible and put a good filter on it

True story right there! 98% of the time it turns out to be a mechanical issue causing the complaints. I have had customers drive their truck to me to prove my charger was not working properly only to find bolts hanging out of the up-pipes... Stupid shit happens everyday unfortunately, you'll find the issue buddy!
I've looked for the stupid stuff and no luck yet. Rob, that's the next step for me, a pressure check. It's got to be the y bridge or intercooler itself I'm afraid. Couldn't be a cheap boot for me. Why are a couple of you guys saying WIX isn't a good fuel filter???
I was running the truck today on the performance tune and once it actually picked up and ran. I'm lost on this thing right now.

The wix plastic fuel filter is junk in its design. The plastic housing can crack and leak, the oring flap crap in the center of it it's stupid design.
The way the wix filter is it's actually possible to install it over a gm style oring and have a leaking system (air) which In turn can kill pumps.

If its intermittent then its an electrical problem or a bad or poorly functioning sensor. Scan your maf sensor or better yet clean it then go run it...
I've cleaned my MAF a few times now. Crawled all over, under and inside the engine compartment. Spraying carb cleaner on the boost tubes and fittings to try and find a leak. Changed out a fuel filter with 2k miles on it, then changed out the fuel filter housing. I don't have any codes. 
You need to apply pressure to the inside of the boost tubes. Spraying the out side is not going to do anything unless there is a serious hole.
Well I'm also thinking it may not be a boost leak because the truck will build 22 or 24psi at max but it just takes a few seconds to SLOWLY get it there. Like there's a restriction somewhere. But the turbo I'm running is suppose to build 35 if my tuning is supporting this.
But what do you mean apply pressure to the inside of the boost tubes? I had my son holding a few rpm's while I was spraying.
