have any of you tried those performance chips that trick your pcm to think the air temp is colder than it really is? i imagine it would just ruin your gas mileage dumping that extra fuel, but w/ a 4.0L throttle body, ram air intake, and maybe a header i'm thinking i could get an extra 15-25hp. if anyone has a wild hair and extra $600-$700 to try it let me know how it goes.
