Fuel pressure increases using race fuel

This one really throws me. I have two tanks and a switch to change tanks on the fly. While programming my EFI I noticed the fuel pressure increased 2Ibs when I switched from 93 to 112 octane. This changes the A/F ratio about 2 points. This makes the engine run much richer on 112 octane. Does race fuel flow better? I would think the fuel regulator would balance this out. I managed to get the programming to work, but this confuses me. Any ideas???

Are you talking about race fuels or all fuels.
