I've done some research on this topic. The only product I would suggest would be the Edge Products Trail Jammer Kit; it comes with a CAI, larger throttle body, and chip for $350. I don't have one myself, but I plan to get one because the majority of the people who get it claim a noticeable increase in power and a slight increase in MPG.
The only other feasible option I came across is a Jet chip, but people who purchased it seemed more split up about it than the Trail Jammer. Even the ones who noticed any differences in MPG and power said they were only minor differences. And the chip only is $200. It is probable that the Jet chip works better when you put install other mods, but I'd say just spend the extra $150 for a greater guarantee of a larger increase in efficiency. Also the chip that comes with the Trail Jammer is designed to work in conjunction with the provided intake and throttle body.
Anyway thats my 2 cents. How long is your deployment? I may have the Trail Jammer Kit by the end of summer if you are still thinking about getting one yourself.
