Extremely happy with my Mission Performance Stage 2. Outstanding performance on pump 93 octane.
21psi by 2600rpm, slowing climbing to 23.5si by redline. 6-8 degrees of timing advance through most of the RPM band.
On E30-E35 net blend it gets even better, and timing holds steady with 10-12 degrees of advance.
Brand new 305 P4S feeling the pain.
