A wideband AFR gauge is your best friend. Right now I just made a new one with three return jets. A low, medium and a high speed. Low will be set around 3lbs, medium will be set at around 15lbs, (that's where my fuel pressure is at when cruising. It is a little fat right now, the high speed is set around 40lbs. They will all be returning when I smack the throttle. When I added the high speed the engine really came to life. Can't wait to try this new one.
