High Octane Gas

wont do jack for you unless you have a chip that can take advantage of it...
stock ecu will run cherry but its programming is already optimized for the 91/93 octane world.
With a chip and switching it into a high octane mode, 100, 104 program it will run a software optimization for the better fuel.

Definitely not as much to gain but the stock ECU will pull back 6 degrees of timing or so...
under hard driving so the added octane will benefit, just not as much as if you had a race program.
