Any and every parameter can be changed with a chip (or aftermarket PCM - if that every appears) The chip basically acts as the set parameters for the PCM. Instead of the PCM using it's own (factory burned) parameters.

It's just finding out where they are in the original code (many 1000's of lines) and then figuring out how to change them. This is why just popping in a chip is so hit and miss.
It would take a ton of hours per each computer code just to make a good baseline program to start with. Then tuning it to your exact engine and specifications...

Dyno tuning a custom chip for your car will give you the best performance gains outside of forced induction! (or more displacement, but that's a different motor then isn't it)
