Tuning Zonda GTS and Zonda R

Hey comunity, I’m having issues tuning the Pagani Zonda GTS and Zonda R for use without assists ie: TCS, ABS, and STM turned off. I’ve been messing with the differential and tire pressure but to no avail. I’m good with throttle control but need to figure out how to make both cars stable/ grippy on corner exits. Any tips/ help will be greatly appreciated!

Could you possibly give me some more detail on the tune please so i can get a better idea of any tips i could give you .
