As per my request the dealer changed the engine oil, drain and refill trans (MT-82), drain and refill diff. Also decided to have the dealer install a Track Pack diff cover while they were at it. (Mine is a Brembo GT, not a Track Package so it has 3.73's and a regular limited slip instead of a Torsen, and it comes with a basic steel cover)
I'm sure there will be some folks that disagree, however when I build a customer's car I change these fluids at 1000 or less ...(Not always trans but the MT-82 needs all the help it can get)
Received the Track Cal with voucher and K&N filter next day air from Auto Nation, registered myself and the car with Ford Racing this afternoon. Called Ford Racing to verify all is well and they are overnighting my Pro Cal tuner so I should have it tomorrow assuming they got it out the door in time. Now I just need to set my appointment with the dealer to have it installed. ~Also in the picture is a track key that they also shipped in the same bundle for a friend's 2013. He did the cluster swap on his.
Just got a 2014 GT myself over the Memorial weekend holiday. So far, it only has the GT500 mufflers and a white Barton shift ****. A set of Eibach Pro kit springs, panhard bar, Barton short shifter and Energy Suspension transmission bracket bushing will be installed on the 28th.
Enjoying my Track Cal. I drove all through the Sierra/Nevada mountains for the majority of last 3 days, burned through 3-4 tanks of fuel while still getting over 20MPG like before. It did obtain a check engine light with the Cat Efficiency codes on day 1, cleared them and they have not come back after 2 days and 2-3 tanks of gas. The car performs much better in all aspects, especially engine braking and throttle response. My only complaint is how long it takes for the lopey idle to activate. I also noticed if you "nearly stall" the car with the clutch as I did today on my way into the garage, it WILL shut off the lopey idle and require you to wait the 130 seconds before it kicks back in. There must be a minimum rpm requirement, or it must have thought I actually stalled the car. I'm sure this tune will have a few bugs and in my case I have plenty of warranty left to deal with it since I'm at 6k miles. I would think Ford Racing will eventually patch any issues if part failures arise, or if severe drivability issues come up. So far a few codes and no other issues and I'm definitely happy. I have not yet tried the launch control or pit speed limiter.

Ray from the Ford Racing Tech Line has chimed in on the link above regarding the catalyst efficiency codes and Check Engine light. Sounds like FRPP has it figured out.
Cats should be fine, there is an issue with the software that is causing a "false positive" during catalyst monitoring. I talked with him in depth over the phone and it all makes sense.
They are issuing a revised tune in the next week or so for those of us that have the problem. Nothing should change in terms of the lopey idle and other performance + everything will still remain smog legal.
Not everyone will have these problems either, just a handful. Good to hear they are fixing it.
As per Ray's permission, here is a snipit of his post with his contact info for anyone that has the Track Key/Track Cal...
"There will be an updated calibration that will take care of the false codes for cats. The cats are not being damaged.
Please send me an email with full name, VIN and shipping address, when the new cal is released I wil make sure everyone receives it. Not everyone will see these codes but we want everyone to get the new cal to make sure you dont ever have these codes.
