Going to just a higher octane and nothing else, will not give more power, on a stock yaris. Now if other things are changed and modified, that's a different story.

The only reason why a higher octane would give more power, is if the car was compensating for detonation, running rich. Since our cars are designed to run on lower octane, nothing happens by using a higher octane.

yes, running higher octane does not do anything but running higher octane, larger injector and advance timing or controling fuel does make a difference

A front strut tower brace will offer no improvement on a Yaris if you are still using the stock upper strut mounts. You have a strut that is mounted in an inch thick rubber doughnut, that is not even positively affixed to chassis, the damn thing just floats in there.

Replace the top mount with a proper bearing plate first, otherwise you are just burning money.
