a/f meter in car using 110 octane

Anyone have one mounted in there car?? Seems to be a argument about diff. Octane levels and a/f readings, we have a dual sensor fast meter and at wot were running 12 to 1 ratios with 110 and 34 degrees of timing. Thanks steve

I run one installed in the car and it runs about 12.5 average out on the road.
When I get into the secondaries it drops to 10.5 average, so I'm going to drop a size on the primaries and see where it is then.
Might have to drop a size on the secondaries after that if it isn't closer at wot.

Sound like you could drop a size on the secondaries, as long as the low and part throttle A/F is pretty good.
