He's referencing some tuners that claim an extra 140 hp. Not possible with stock injectors and turbo by just a chip's tuning. Injectors have about 60-65 extra in them at most, might get up to 80 total with a modded turbo too, but will still be billowing black smoke. They usually change the FIPW really high, which on a WOT run ICP will drop in higher rpms.
But since you say you aren't chipped and are stock FIPW shouldn't be so high.

I also need to replace my sway bar links, look over all other previously installed hardware I did.....just to make sure all nuts and bolts are tightened.
If i missed anything guys, PLEASE let me know!

Could be the P1316 is an old code. If there is a kinda fresh UVCH from the PO then they replaced it, possibly due to the fault. Clear codes and see what comes back.
Correct. With the injector out there is a hole for the fuel/oil to escape. Don't need 2 holes.
Just noticed you're in SoCal so the temps are mild, so maybe dino vs synthetic oil is not critical. Unless the injectors are old as frikken Yoda and just done.
Say more about "blowing the ICP". I don't know what that means. Unless you have some mods like a billet turbo wheel and tunes that raise boost enough to caused defueling (23psi or so is the threshold, stock max is like 15psi) you don't need a boost fooler. But now that you have it, you should get a billet wheel and some tunes.
IPR, EBP, HPOP, and trans values look good for idle after a WOT run. The lowish number of 8 for IPR I'll attribute to the cheapo ICP. Should be more like 11, but it's not a concern. MAP I couldn't tell ya. InjPW is goofy but if it's just a decimal out of place then it is a concern. 2.6 ms is fine but 5.3 is ginormous and indicates a hot tune run amok. Ideally we'd want to see a graph of ICP and HPOP during a WOT run. If the ICP drops off under WOT that's a good sign of crappy tunes. Immediately after WOT the ICP will spike, and the 3k psi max on the gauge is pretty normal.
If you want to spend the next 3 days dorking around with Torque Pro on your cell phone to get the output readings fixed, check out this thread.
Do you have gauges other than TP?

Those numbers look normal for a truck that has been started with TP running. If you hold off starting Torque Pro until the engine is running, then we can see the min/max on a running-only engine. As awwlberininf350 mentioned, a log of the truck running that includes a WOT run up a hill can tell us a lot. Torque Pro is tricky to set up logging, but FORScan is a much easier app to work with for troubleshooting purposes.
I will be in total amazement if those injector O-rings don't need to be replaced. You can search "Cody test".

Almost for got to ask, is there anyway to get more info on my P1316 code? Something new came up and it said P1316P

I think that the IDM might have codes too if you can read them.
I had a P1316 once right after I did some injector work. Truck was idling and running rough like it was missing a cylinder. Pulled the VCs off and found that I knocked the clip off of #7 injector when installing the passenger side VC. It's a tight fit to maneuver the VC and I wasn't as careful as I had been in the past.

Here's an old thread about the code:

Is there a way to check the IDM alone?

Do you think it’s worth it to change out the injectors that come up bad on a buzz test?

Ill echo what Tugly said, do the Cody Test. This will rule out any bad orings b4 pulling injectors.

Thats the air test with the VC off while cranking the engine but not turning over, right?

Cody test applies max available shop air into the head where the high pressure oil line from the pump goes in to pressurize the oilway around the injectors while you listen very closely for gurgling noises indicating oil leaking past injector orings
