My experienced advice/comment,
Keep in mind that in the many gear swap threads there are also many different year/model/engine applications that likely differ from your exact application and your results will vary.
I personally went to 3.73 from 2.73 in my 2013 V6 auto expected MORE SOTP feel than I achieved.
With this gear swap I didn't expect the gear whine and DS (or split bearing?) hum in top gear cruising speed that I now have.
I have since been told a couple interesting things by a Mustang mechanic and previous employee of a local service department. One of the highest number of valid returns and redo's were from gear swap customers.
Another item he shared, which I'm not sure how true it is, was that even with a perfectly installed set it is a "roll of the dice" for 3.73 gears in particular on the amount of whine you'll experience.
Lastly he and others I've spoke with on the subject tell me that Ford now outsources their gear manufacturing to Motive. Funny the shop I used required I purchase FRPP and now I learn that they're all made by Motive?..
Anyways theres my input FWIW.
