unless you have a dyno no way to really tell i would just try leaning it out a couple percent througout the whole rpm range then at the cross over have it richen up 3%

If there's no way to tell without a dyno run (AND wideband a/f readout!), why are you giving advice on leaning the fuel curve??

Dude, seriously, don't mess with the fuel delivery to your motor unless you can get it to a dyno to know for SURE which way to go i.e. lean out or richen it up.
