What was it in that quote ? You can but 4.09 Ford Performance ring and pinion for less than $300 - which is all you need. Not sure this takes $1700 of labor. Calibration is just switching gear ration uding ProCal. Pretty sure I can do it in my garage and all it does is ensured speedometer indication is correct - which if you ever install different diameter rear tire (people often do), it will be off anyway. I would send an email to Ford Performance to confirm this...
Honestly I don’t feel a huge difference, but I don’t have a ton of miles on the car and already have a Borla cat-back. Maybe I never got a good feel of what it felt like stock. The shifting does seem more aggressive in Sport mode and my 0-60 time improved by 3/10’s so it’s definitely a little faster. Still playing around with that, trying to get a cleaner launch.
I will post more of my thoughts and impressions on it after I have some more drive time with it.
Installed myself with help from my girlfriend’s dad. I think he was more excited about it than me! Maybe 2 hours tops. And we even took it back out and refitted to make sure since the orientation of the new throttle body looks different than the one shown in the instructions. The instructions show the stock TB. The longest part was saving the stock calibration and uploading the new one. I’d recommend having someone help you, especially to hold the tubing in place while you clamp it down to the TB.
