the timing all depends on what the car likes and what gas and everything you are using , did you get it tuned ?

your WOT timing is much easier to determine. Your daily driving acceleration tables (especially at low loads) are the biggest problem when running high compression and pump gas. Your engine will react differently to every other high compression engine all dependent on the breathing mods you have and the quality of the premium fuel you are using.

my advice is to tow your car to your tuner and have him do it.

this is an H, not a B. And you dont know what engine management he is using or how it is configured to operate the ignition timing.

on that note, my WOT timing saw 33* with stock ignition corrections disabled above 550mbar on a little over 12:1 compression.
