Did some logging. My trims are all in the -9 to -15's in the lower half of the map values. I can understand my volumetric efficiency being less than a stock heads and cam at low rpms but it seems that by 4000 rpm, my engines VE should be better than stock? Is this typical for a heads/cam engine? I have long tube headers, how much does this effect the accuracy of the O2 sensors?
