You can take out the speed limiter if applicable and change rev limits. If it is an automatic you can modify things like shift points and line pressure to firm up shifts.

But to modify the tune you must first figure out what to modify... Changing fuel parameters and timing without knowing what effect it will have can damage your engine. Having data logging software would greatly help.
