Too Much Fuel, Too Soon? And Other ???

[theSLEEPER]

Just wondering.

Without CP testing equiptment, how would you know when it was too much fuel?

Let's say, Stg. 2's, with known good injectors and nozzles, and something like a 38R.

Wouldn't the sound be enough to tell you something is wrong? I know that I can hear the difference in SOI or "timing" when switching tunes.

Would severely advanced "timing" create a better running motor? Or would it just cause excessive heat?

What about excessive ICP along with excessive "timing"?

Does increased ICP create advanced timing? All else equal.

What about IDM mods?

I'm sorry, the title may not be fitting for my questions, but I'm trying to gather all I can as soon as I can.

Could you create a more quiet and less smokey running motor by delaying SOI and calling for less fuel? Would that cause excessive lag?

I guess this is all more "theory" and not pertaining to Minotaur, so if it needs to be moved...

Thank ya'll in advance!!!
