So much to argue about and so little time:-)
So the OP is looking to mod, learn and spend his money wisely. Some of that is subjective so he needs to follow up and research each mod and make his own decision. As I read his post he isn't asking about big power just yet but I agree it is important to look at the big picture and have realistic expectations. While many of the minor mods were expensive when you were on the leading edge of the performance effort for these motors, they can now be found used for cheap. That goes for the big mods too or even a motor swap but its all relative you your budget, goals and skills.

An awfully presumptuous and condescending comment. Of course I keep that in mind. Can you remind me what cars I've owned & worked on?

Unfortunately "very well" is relative to something he doesn't have so that's a big problem. He'll have to answer is 'very well' good enough.
You learned that big power costs big bucks. That's so cute:-) (busting your ***** here) Duh, we all had to learn that and so will the op. Goals should be realistic but he may have goals different than yours. Or, maybe the same as when you started.

I'm all for a flash tuner, personally I just think of using a chip for these cars, consider it a flashback if you'll pardon the pun. I see at least one chip is still available, btw. The point was how to make those changes. The tech tools to make the changes evolves but the principle behind making them hasn't.

Who did the your tune, I think I might want to avoid him:-) If this was a custom 87 tune optimized for you then I can imagine little change to peak # with the 93. More to the story than peak #'s though.

I prefer to argue that a dyno is simply an advanced tuning tool and not the same as real world driving experience. A singe rwhp # data point with out any overall context means nothing. You need to examine and improve the entire power curve and expand the power band. A more important # to know is what was the change to your avg rwhp? A motor is only at peak HP a small fraction of time compared to the rest of the time its making power. Next to consider is HP means crap to these cars, more important is what was the change to your avg torque #'s? A small motor and heavy car needs torque improvement NOT HP improvement? Maybe those numbers were unchanged as well, I don't know.
All in all I agree with your end game but that may not be for everyone. I agree you really want to consider cost/benefit but think you can do a lot of little things for not a lot of money if you are smart. Yes it may only be little gains, but he is going to be modding and evaluating and learning.
