Yes, any car with adjustable timing CAN get more power by advancing the timing a bet more than stock and using higher octane fuel. This will not give better fuel economy however

in my caddy i used to run 87, it ran a lil rough, and mpg was alright.
i tried 93 on it(since the motor has 10: or 10:5.1 comp), and runs way smoother, and actually got better mpg out of it.
now all i run on it is 93.

timing has a big part in it also.
when switching my old street strip car from 93/114mix to just 114 i would have to move the timing 5 degrees..the car ran a ton better on the 114 though..
dont try and run 13-1 comp on 93 if u dont have a clue what your doing..
