Superchips are good, and i know Bully Dog makes a good gas tuner... tuners are extremely effective on diesels, not so much on the gasoline engines but they do make a noticable difference. On a gas, the tuner will give you anywhere from 15-30 HP, and i'm guessing the Superchip has different performance levels. I have a Hypertech on my old body style Expedition, and it makes a small but noticeable difference on the performance. It will also give you up to a few extra MPG. Sounds to me like you're ballin', so go ahead and get one. Good luck buddy
