91 or 93 fuel custom tune question
Does anyone have any input on which octane and tune use in a daily driver when getting a custom email tune 91 or 93? All gas stations in my area sell 93, but I want a tune that will give the best drivability with a little more performance during the summer months that I drive the car. Thanks
