Depends, as a racer I set the pump to max out at full throttle for obvious reasons.
The pump should be set to the calibration mark for street use though...
As for jetting, you may get away with it, but you will certainly benefit from checking and if need be rejetting after any mod you do. Suck it and see really, but be aware of the consequences if you don't check your plugs after the mod!
