What I found from my testing is I could run a small amount of N2O at light load on my lean burn engine and retard timing from 38* BTDC to around 6* BTDC at a 25:1+ A/F ratio and improve BSFC. What it did was make my already fast burn head faster. Running a lean burn engine requires more ignition advance and that is not a good thing. The nitrous help with this.
The down side with nitrous oxide at $30.00 lb. for a 10 lb bottle, the cost doesn't out weigh the improve engine efficiency.

How does a faster combustion event lead to an efficiency improvement? How have you measured improved BSFC? This sounds like an opportunity for detonation, which will not improve fuel economy.
