Just want to follow up with this thread after doing a manual gas mileage measurement to validate the computer, and after 2 fill ups, the 27 MPG in the computer is accurate! I'm pleasantly surprised of the 5 MPG jump after they did the service, but at the same time I'm wondering if they can "accidentally" set it back to the way it was the next time they do a service. Only time will tell.
