This is not possible.
The cam with the best low rpm response is the stock cam that has no overlap. Any cam in a turbo motor that has overlap will cause reversion, which impacts efficiency at low rpm.
The SC cam enhances power in the mid range. The 964 is best mid to top. Both do not function as well as the stock cams at low rpm.
Cams cannot affect compression since they are closed during compression.
