mpg tested before 26.3 after 27.9 (same route) on 87 octane. will pay for itself. manual didn't say what port to install it. customer service only open during the week, so plan ahead. just wish they idividualized the installation manuals more. sometimes requires a little more work on installing. '09 fusion users, top port and must remove at least 1 bolt from battery support bracket to rotate it out of the way to get module plugged in. battery bracket will go back after module is plugged in.
