TS: what is the stock ignition advance at WOT ?

Hi,
Would someone know the ignition advance stock TS engines must have ? According to OBDII I'm getting 21 degrees on my 1.8TS from 4000rpm up to 7000 which looks low. 1.8 or 2.0 should be close to each other.
If by chance you had the air flow at WOT I'd be interested as well.
Thanks

I know my GTA is advanced now to 13degrees. And over 30 when you blip the throttle. I read an interesting artical from Bob dove re ignition timing and he was saying that due to the crap quailty of fuel these days ignition timing was advancing more and more. Not much help but my point is that even if you did find the basic set up it probably wouldn't be of any use anymore.

Thanks but your GTA is not the same engine.
Sounds strange to advance ignition for a crap fuel, it's the opposite that you want to do to avoid knocking.

I actually found a M1.5.5 and extracted the ignition map.
Well I don't know how to properly format the table in my post, but it gives
