its not that hardcore.. just fill your tank up with 91+ the week before you load up the tune or something. Your car won't break down if you put 91+ octane in it when its not tuned it just won't help you any but waste your money.. if you do it long term i suppose it could cause some damage. Also you don't have to do a premium octane tuners recommend it but its not needed like I said I have a 87 performance, 93 performance and the 3rd is either 87 or 93 gas mileage i forgot which one exactly since i haven't used it. and the tank doesn't have to be bone dry gas is gas it makes the car move. it can mix just wait until it gets a little less than a quarter of a tank or something haha
