Both. The timing "Sweet Spot" is a point you don't want to exceed. If you want more speed, you can gear it up. If you want less speed, you can gear it down and/or turn the timing down. The biggest thing to look at is the motor temps. Some like to run their motors to over 160*. That's pretty freaking hot, but you gotta do what you gotta do to keep up. The problem is, heat weakens the magnetic strength of the rotor. When the rotor cools down, the strength will return, but not all of it.
You can tune a motor higher, and it will go faster. The downside is, it will not be very efficient and will get really hot, really fast.
