frankieb96 - Pretty much as you mentioned, however if the gas you have been using is of poor quality then yes you will feel a slight difference. Also, if the weather is cold, higher octane will help a little to take advantage of the denser air, given the ECU has any timing left in it's operating parameters to throw at the situation.
Now, if you have a pulley and some ECU tuning, then yes for sure, if the ECU tuning was set up to take advantage of the higher octane! It's all about moving Peek Cylinder Pressure closer to Top Dead Center to take mechanical advantage, as much as possible, of this Peak Cylinder Pressure event. -
