This may be an example of your just not having enough time to find the correct adjustment for the conditions. With more weight, the rear should be stepping out more, all other things being equal. More weight = more lateral load for the tires to manage.
This is very similar to when we ran weight in the B4 with lipo until the team found a setup that worked better at minimum weight (ironically, pretty similar to the base setup of the original B4, when 6-cell batteries were lighter than they became).
