Im not sure why but more boost = more power even though the overall cp is the same. My guess is that its less of a fighting force as the piston comes up so less power is waited on the compression stroke. More power in boost less power out of boost. |
I run 12.5:1 with a boost level that is in the "red" on your table. Knock is definitely not an issue... you may want to investigate why you're knocking at just 10 psi.
