- Mon May 25, 2009 12:11 am #118575 The only way to know is to use a dyno. No two engines respond the same. And going in either direction invariably helps you. The problem is that you gain in one part of the power band and sacrifice in another.

It's not as simple as adjusting each one a certain way. Adjusting one affects the valve overlap between the intake and exhaust. Overlap is good in the high RPMs of a N/A engine. Bad in the low RPM's, and bad for forced induction.
