We experiment with several new modifications to the Baumgarte-Shapiro- Shibata-Nakamura formulation of Einstein's field equation, and demonstrate how these modifications affect the stability of numerical black hole evolution. With these modifications, we obtain accurate and stable simulations of both single excised Kerr-Schild black holes and punctured binary black holes.
