911st, I don't think I've ever heard of a cam being described as altering CR. It does make sense though at low rpm.
However, increasing the engines CR to compensate for a wilder cam must mean that when the engine 'comes up on the cam' the CR will be higher than it previously was. So when the engine is on boost you must need to lower the boost level too?

TIA
