Free mods off the top of my head:
Proper air pressure.
Advancing timing over factory setting.
Gutting air box (which you probably don't have).
Modified air cleaner (https://www.thirdgen.org/newdesign/tech/ultimatetbi.shtml).
Remove unnecessary weight.
Of course, if you don't have a timing light or Dremel, these aren't totally free, but after you buy the tools, you'll have them for other projects.
Other examples are improvements over standard replacement parts, like performance ignition components when you do a tune-up, free-flowing air filter, or my favorite, synthetic lubes.
Some low-cost, almost "free" mods: Dual-snorkel air cleaner from two old single-snorkel, homemade adjustable fuel pressure regulator.
