I been doing more and more on my own and saving TONS of $$. How would I get the tune knowledge in my head..
(I was thinking tuning had to do with the ecu + all your mods that can equate into the HP/TQ Performance factor)

Your car can only perform as well as the software tells it to... shitty tuning equals shitty performance no matter how good the hardware you've put in is.
How you tune varies a bit from one system to the next but the overall target values remail the same... when you get past the basic "get it running" level the tuning becomes very specific to that one engine... every little unique thing and all of the end desires require someone who car really feel it out more than just rust read the numbers and press buttons. I can't really recommend any one good source for reading up on tuning... haven't found any really. You just need to learn the theory and start doing it. I did read a bit and I started tuning my old N/A then I tuned a friend's car (retuned both of these MANY times) tuned a built Supra out here.. then another... and so on. Start with some "seat of the pants" tuning with an old Honda and then try tuning on a couple dyno runs... THEN work on the Supra.
This isn't one of those things I recommend that people do themselves... a couple digits off and next hard run you've melted a piston. It's a good thing to learn, but a lot of care must be taken.

I want power and reliability.. I don't want to keep having to crack her open due to other failures. I would like to get it done right so she runs the marathon hard and long!

You're really fine with a stock build (maybe some slightly more aggressive cams). I'd rebuild the bottom end (by the book), replace oil squirters, oil pump, pistons and rods would be excellent; and then I'd aim for the upper 300's.
