So C16 on a NA setup will not make a difference. So im guessing it'll only help with a turbo setup and lower compression? sorry im a newbie when it comes to when C16 is ideal. :)

Just my guess. The use of race fuel will only benefit performance if the car's ECU has areas of the timing/ignition etc maps for it (which it probably does not), or if the car has force induction, heavily modified NA with higher compression ratio than stock.

The stock ECU and all the rest are optimized for the recommended fuel and is not capable of adding more hps out of higher octane.

Anything over 95 octane for mildly modified NA is probably over kill imho. Save the money towards other things.

Reducing weight will definitely help, you accelerate faster, stop faster.
