Got some modd list going
. Ya know TOG are sick. BuT the cost, SLP are nice too. My buddy had a set of both, TOG on his last set up. This ones he just purchased SLP duno how it sounds. A tune is nice cause it is set up for your car, but your better off getting a pre tuned. If you start getting into like a cam, or some heads then a tune is best. If your into tuning your vehicle your self you can purchase a dhp tuner and tune your GP yourself.
