Can someone help me understand the fuel table for a PCIII USB. I'm was looking at the powercommander maps for a touring bike with true duals, samson ovals and SE air filter with and without the stage 1 ECU. The values for the stage 1 ECU are higher than the stock ECU. If the stage 1 ECU richens the mixture over stock, why would the numbers be higher for the stage 1 vs stock ECU? I would have thought that with the stage 1 less fuel would need to be added.

My understanding is that the numbers represent a % increase (or decrease) in the pulse that the injector feeds fuel, is that correct?
