If you see a speed governor, you can change it. If you don't see one, you can't. That's really about it. Nothing really else to say. It should be pretty self explanatory.
As for boost, you can lower the boost target map or lower the wastegate duty maps, but the car will still reach "wastegate spring pressure" if floored. This is probably 7-10psi. I'm not sure on EVO's. Either way, you can't just disable boost just with the tune, just keep it much lower.
That's about all you can do. There is no magic wand to turn the car into a Tercel.
