Yup just like everyone said. I was wonderin now that I have my intake and exhaust which gas should i be using? I use themiddle one here I think its 89 or 91.
Oh ok cus i guess its just cus i drive like 15miles to work thats killing me. I just wanted to make sure if changing gas octane is good. I use 89 or i would have to fill up twice a week.
