A Couple of rare mods would like your opinions with.

Which can only be done with a higher Octane gas.

No. You can have it tuned for lower octane. My Z has 2 tunes. One for 93, and one for 91 octane.

It's already tuned for the available high octane here. And the results were poor and not justifying how much the tune costs. So if I want a better tune, I need a better octane gas.

What I've read so far from almost all the people who tuned with EcuTek that the gains were great over the stock or even Uprev tunes. But what I've gained with EcuTek over the stock is just ridiculously low.

Read what you just wrote. You need a better tune from someone else.

Let me point something out. The first tuner who tuned the car was John Visconti. The second one is Sebastian @ Specialty Z who I consulted about the tune and he literally said that "the engine knocks rather easily. This is why it's not making more power". And then he suggested "to run higher Octane and perform another WOT log. Check the knock corrections. If its OK and you get 0 correction try running a more aggressive map and repeat logging". And I did that. It's all written in the OP.

Now both John and Sebastian pointed out that the fuel is the issue and no more power can be added unless I run a higher Octane fuel, I guess this is a good reason to look for such mod.

I asked Sebastian about the water/meth and this was his opinion: "We don't like water\meth because of the negatives it can bring, more so on a forced induction application. On an NA I've never tried it to know how well it may work. It would definitely help with knock and keep temps cooler. May not be a bad idea. There is less risk on an NA engine as well."
