If you don't have a tune for that octane, high timing or serious compression, it won't be worth it. It can actually hurt performance or if you still have cats on the car, unburned gas can actually damage them. I would stick to the recommened 87 till you atleast bump the timing or get a dyno tune.

never use more octane than the car requires otherwise you can cause damage to the car and you will be throwing money away....
