Oh my goodness, the fire has been lit again! I have some discretionary funds this year and have always wanted to change the rear gears to the optional 3:55 gear set from the 3:31 set and add the Ford Racing Diff Cover, like on my previous '98. Car has just under 26k miles and I still have the Superchips handheld tuner that came with the car. I seem to recall something in the menu about 'gear ratios' - hoping that will correct the speedo.

Car will have its upcoming annual service (rarely drive 3+k miles per year); still needs its RH airbag replaced, state inspection and I'm thinking about having the stock tune checked to see if its the latest and greatest. Same goes for my Superchips tuner as its one of the first released for the '05 model. I'm a bit leery about this last item as my bike dealer downloaded the most recent tune for my '08 motorcycle last year. While it doesn't run bad, I seem to think it ran slightly better before!

My grown daughter wants the car but a new '18 GT well equipped is around $50k I've read so that's out of the question at the moment.
