We dropped the AFR to 3.2 The idle went up by 300 RPM over the 9% setup (with no idle adjustments).
With a small increase from 6% to 9% nitro, in preparation we dropped the AFR to from 3.7 to 3.4. As a result, we picked up a tenth of a second and about 4 MPH over 6% nitro.
We added port nozzles and put about 60% of the fuel into the ports.
