You'll have to get your PCM unlocked or buy an unlocked one to use a tuner on your truck. I don't believe the tubes are worth the money if you plan on using just the canned tunes. If you get one you'll also want to get a custom tune for it. What are you looking took get out of a tuner?
That's for all the reply's. I do like the look the the Vararam so that may be a winner. Exhaust is still in the air as the truck is still new and I just cant see spending a ton of money on that. I need to hit the lotto and just be done with it. Thanks again fellas.
