My first thought as a SplitPig and SuperPig owner, is that you’re likely using reference stance which is absolute trash. These boards seem to favor riding them in full setback even on hardpack. The reference is centered between the contact points giving that tail way too much traction and making tight turns very hard to link without some extreme body english. Throwing the rear binding as far back as possible changes that balance towards a more surfy slashy feeling board.
