Need help on ignition table.

I've been tuning my own standalone for some time and I recently drove it 4000km on a road trip. I need to adjust the lugging zones. Going up a hill in 4th or 5th gear.

What is your timing in the lugging zone? I set it now to 10 degrees from 500-1500 as an emergency fix.

I get peak power around 3000-3500rpm so I really struggle uphill high gear.
