I agree. I don't see any effect of my high-speed bypass valve on my Flying Toilet until after the 1/8 mile. But I have it set (pressure and pill) to keep the mixture from going rich the second half of the track. Before the high speed I was getting 11.3 A/F (gas scale) at the finish line and after it was 12.3 the entire track.
