I just filled up my car with the usual 98 octane and added one of those octane boosters to make it 101 octane. They results are very noticeable!!! The car just wants to go by its self almost and its so much more pully through the gears. 3rd is now seriously good fun!! I cant imagine what this effect would be like in a 3.2!! There is an octane booster to make it 104 octane..... should i dare it!?!?!?!?
