But, it will also show you the natural spooling of your turbo and at what points you want to start adding wgdc, so that it keeps the wastegate closed and allows you to build boost past wastegate pressue.
Ok so to pull timing, what needs to be done in the ROM and under what table/options. There are three tables I see which are:

Ignition Timing - Advance
Ignition Timing - Compensation
Ignition Timing - Knock Control
