I remapped the exact same car with Superchips Bluefin, adds 45 BHP and is easy to add/remove yourself via the diagnostic port.
I ran the remap from 25k miles to 98k miles with no issues. Performance gain wont turn it into a monster but it is much more pleasant to drive and you will appreciate the extra power. Oh and MPG slightly better (I averaged about 39.7 mpg from 39.2 mpg before remap and I do like to put my foot down)
