instead of pulling numbers out of your *** its better to use gm curves from various bins and maybe make % differences to them. I made the mistake of just pulling numbers out of thin air to make changes to some things like pump shot, coolant afr in clsd loop, map afr adder in closed loop etc and i didnt improve the situation, driveability became a little shoddy, ive reverted to gm curves and have instead made % changes to them or done like an "inbetween" of two different tables and the difference is night and day.. much better results this way i sorta liken it to tuning a carb with off the shelf parts vs fabricating the parts on your own

 

Also helps to view the tables/curves graphically to get them "similar" before and after modification. Like on TunerCat.
