kind of interesting numbers from the lower boost pull:
Stock figures are
212hp @ 4600rpms
275ft/lbs @ 3000rpms
With the turbo it reaches the naturally aspirated max's even earlier at:
212hp @ 2845rpms
275ft/lbs @ 2657rpms
And the max hp comes in 1100rpms earlier max torque is 400rpms later but there is plenty of it:
384hp @ 3466 rpms
570ft/lbs @ 3400rpms
Very happy with the outcome, I think you could maybe go a step up in turbo size and still have a very drivable truck with a great power band and make even more power.

Forgive me if I have missed this, have you guys done anything to transmission?

Should give you a decent idea of how they'll hold up to your 12 valve, I had the same thought.

Same shift kit lilevo used on his truck and he is close to the same power levels.

That's one sweet build. Impressive numbers on a mainly stock long block.
You're on the right track with modding the tranny next. As long as you roll on the power, the drivetrain should be fine with that mod.
On a side note, have you considered adding methanol/water injection for insurance while hitting the "high" boost?

Really no need at my boost levels with the low compression motor, the ignition retarded and the cool air from the I/C to bother with meth injection.

Here is a video from one of the mechanics that was there for the lower boost dyno pull. This would be around 384hp.

I was wondering something similar: would not an 80 turbo application that is without an intercooler substantially benefit from water injection, particularly without engine management (something simple like 2K's)?

Yes if you don't have a way too cool the air like an intercooler you would benefit from water/meth injection but it is a very touchy thing in most performance car builders minds because if you loose a water/meth injection system you usually lose the motor when pushing it hard.
There are systems that have fail safe's built into them, but if you have a leak, run out of water, clog a nozzle, water pump dies, etc it could be a bad day.
BUT if you are not going to tune the system up past what the stock system can handle, and then are just adding it for a little more safety that is fine, but it would have to be used as a safegaurd not as a way to add more power. --- IN MY HUMBLE OPINION---

She squats well on the dyno, making good torque.

Yeah and that is under 8 straps, 4 in the front and 4 in the back. lol.
So after looking at some of the ems powered stuff, looks like the header back exhaust systems provides some of the same power gains as what you were hoping to get from the land tank maf mod. Did you ever consider that or just decide to quite horsing around and bite off the whole enchilada?

I already had it before I tried the Landtank MAF. Lol. Maybe I am just greedy.
And yes it worked as advertised. Before and after dyno in my build thread.

Thanks Ryan. I have run water injection on N/A cars, so I was contemplating this to cool the intake temps within a simple turbo application, but not to gain such a tuning edge that it would be truly dangerous if it failed.

But remember in a forced induction stock system no matter how great or cool your intake air charge is if you don't address fueling after a 20% enrichment by the stock computer you will get a constant CEL.

It's louder but that lack of restrictions is what gives you the power. I really liked the sound but I like to hear the sound of the motor.

Here are a couple videos before the turbo when I put the new exhaust on
