Keith, the core of the issue is to allow the complete system to utilize 100% of it's capacity.
Full travel of the fuel head piston and full adjustment of flow are what it boils down to. We concentrated on flow on the 400whp engine by adding a modded (out of spec) fuel head along with shimming. Result was 12.0-12.2 AFR at peak HP with good idle and fuel mileage above 20mpg on freeway.
