Im a Newb to JBO. Im pretty savy when it comes to cars and have been working on them for quite sometime. I have an 04 Cavy Base model with an auto trans. So for i have CAI, Header, Full 2.25 exhaust, Royal Purple 5w30 and Dexron VI in the trans. I take her to the track quiet often and have done consistent 15.90s but have two best times of 15.74 and 15.76, finally found a way to make it hook with street tires. Off to the track tonight hopefully dipping into the 15.6s
