Yep, that is why a 4.10 (numerically high) is called a "low gear".........it works well at the low end.....
3.08, 3.31, they are numerically low, but work great at the "high end", top speed.

..........and someone correct me if I am wrong.....2.66 to 1 first gear is 2.66 times the engine revs to 1 revolution of the tail shaft, right? or is it 1 revolution of the engine and 2.66 times at the output (tail shaft)? I think it is the first way, but please correct me if I am wrong.....

In 1st gear, 2.66 turns of the input shaft is 1 turn of the output shaft which is connected to the driveshaft.
So in 4th gear 1:1 your driveshaft will be turning the same rpm as the engine, now u have your rear end gear (let's say 4:10) so your driveshaft will turn a little over 4 turns for 1 full revolution of your ring gear.
It's all about torque multiplication to get engine torque to the wheels and to the ground.
Edit: fixed.

Haha you guys are making my head hurt
You got that first part backwards.
U are multiplying torque, your drive gear has to turn more rotations to turn the driven gear 1 full turn (in this case for 1st gear drive gear has to turn 2.66 times for 1 full rotation of your driven gear).
Edit: I goofed yes actually more turns of the drive gear is necessary for 1 turn of the driven gear to multiplying torque I posted wrong in the first part above.

^^^^Yes, that is what I was thinking, that is how we would figure out what a Ford top loader was, or a Muncie or a Borg, put the trans. in first gear, mark a tooth on the output shaft and one tooth on the input shaft and turn the output one full revolution while counting how many revolutions the input turned to determine a close or wide ratio transmission.
I still believe that the 2.66 first gear in the 2013/14 transmission would play very well with a 3.73 or even a 4.10. It is not geared so that the rpms climb so quickly that first gear hits the rev limiter before you have time to shift like can be the case with a trans that is geared at a 3.00:1 range with these lower (higher numerical) gears.
If/when I put a Magnum XL in my 2008, I am going to get the tighter gear spread option for a closer ratio rpm shift range.

I would actually say 3:90 is THE best gear for a 13/14 car with the TR6060 trans. The short time I had the 3:90 in my car I loved it (except for the stupid whining at highway speeds). When I switched to the FRPP 3:73 gearset it was still good but in 6th right at 60mph I could still feel a bit of a dead spot when you try to accelerate without downshifting, didn't feel that at all with the 3:90 gear and definitely no issue if you run 4:10's.
