Please tell me about ignition timing

[NoHachi]

You are correct, only running more advance is not always better for high revs. This is different from car to car..Eg. miatas gain mid-band torque and lose a bit up top when you advance the timing from 12 to 14 or 16 degrees.

Anyway, if you have a 20V running stock 20V hardware (no 4k distributors and carbs stuff) then your advance comes from the ECU. NOT a vacuum advanced distributor. Same rules apply, but like I said, you might end up worse after the mod. Possibly even destroy your engine through detonation. Ignition timing is not really something for back yard mechanics.
