puder, like Biggus said the 525sc has a 7.5 CR and you said that was yours were basically the same. Do you know what your static CR is??? If you're 8.0 then 32* max and anything over 8.0 then 30*. The other thing is that you have a lot more initial/low rpm total timing advance with the V6 module. This will make detonation more of a factor with a heavy engine load while coming up on plane.
