Does anyone know/have a basemap for a D14Z2?

[Threepegasus]

Hi,
Does anyone have a basemap or know which map to start off with for tuning a D14Z2?
Its not a normal engine as its got forged internals and a Y8 head on it, but I thought to start off with its original fuel tables and go from there if thats even possible.

I've used a P28 map for the meantime, but when datalogging and adjusting the fuel table chart is all over the place (Good AFR's though).
I've seen most people saying it can be pretty normal for the tables to be like that, but I thought to ask people with more knowledge than me.
I can upload the map and a log if needed.
