Well i dont have a V6. And i dont have an automatic. But i do have a JLT CAI and SCT tuner. I love it! The race tune is the way to go. It really wakes up the car. It even sounds different when you start it up. I know my car is different than yours. But i think you will experience the same increases. My car just always wants to go now. Very aggresive. The street and race tune are very nice. Performance tune, to me, is nothing special.
And warranty of the car shouldnt be an issue. Because the CAI isnt that hard to remove. And the stock tune take 5 min to load into the car. JLT/SCT is easily reversable if warranty issues arise.
