How to retard timing

[Hellzk9]

Hello all, I'm new to this tuning stuff. I've got a 03 Ba that I've been building and driving for a few years now. It it's purely a track car. Get drifted, lapsprited and I do motorkanas in it. The most I've done in software is a manual swap and PATs removal. I've just finished doing a budget turbo set up. I've loaded a Ba xr6T tune on the N/A pcm and I got the car running. I took it car park drifting the same day and it ran good. Doing a bit of research I've found out that I need to pull 4 degrees of timing out of it due to the comps of the engines being different but I don't know what map to change. There are so many in the timing advance tab. Can anyone tell me which map is the one I'm looking for or do I need to change them all?
