Aside from seriously mucking with the cam timing, I don't think you can. Our cars don't have a distributor, so there's no other way to mechanically adjust the timing. Also, your ECU will attempt to correct any adjustment, so it's pretty hard to do, even with a distributor.

The only real way, that I'm aware of, is an adjustable aftermarket ECU.

the ITC will work to advance timing, but be sure you are careful and don't mind a CE light all the time. It throws a misfire cyl.4 code. But it does work, just needs some serious fine tuning to get any smooth gains out of it.

Would a tec-II or a torque chip cure the ecu from learning over stuff?

Here goes the black box again...

How on earth will the JCS TC2 do anything to ignition timing? If anything, simply resetting the ECU will do all the ignition timing "correction" that the TC2 tends to get credit for.

Back to the original topic:
The ITC is the easiest way to perform ignition timing control. Someone else pointed out that this isn't the perfect solution, since the fuel injectors will fire at the original factory settings, and not compensate for the new timing settings.

The best way to control timing is with an aftermarket ECU such as the TEC-II. Just be prepared for a very steep learning curve that should be course credit for an automotive engineering degree.

Another solution is the Superchips Race Icon... it's a fully programmable ignition computer.

The JCS TC2 would work well for your application.
