Well, I still get 31mpg on the highway (6th gear, 70-75mph) and get 23mpg combined. Maybe there is oomph missing on the low end but since I am not racing the car, I'll never know.
If my engine were going to blow up (like the cooling system) I would do it, but since there doesn't seem to be anything fatal on the horizon, if I can't do it for less than $300, it just isn't worth it to me. Don't mean to sound cavalier about it, but it just isn't that important in the whole scheme of things.
