You want low rpms but not so low that you're below the powerband.

Also, don't look at power, look at torque. Peak power tends to be when you're burning gas the fastest. If you can find the torque curve for your engine, you want to accelerate where torque is high, but being at peak isn't neccesary.

As far as % of throttle, I do pretty well around 1/3 to 1/2, but I'm just using a foot gauge and a butt dyno, so I can't tell if that's optimal.
