Sct tuner is for custom tuning. You have to have a wideband a/f ratio gauge and a laptop. You get custom tunes via email. Great product. In order for you to know if it works on your year model you will have to get in touch with ( Hemifever@aol.com
) .. Sean has been custom tuning for a while now. He custom tuned my 2002 qc ram and I still haven't found one faster on all motor.
Superchips is another great tuner and will have tunes already on it. I have also used this andit worked great for minor mods.
