My 2014 V6 came with 2.73's Like you say had slow launch but good once ya got moving. 120Kph on the hwy was about 1600rpm. Had to downshift for hills. Installed 4.10's, overkill for sure, 3.73's or 3.90's prob would have been better. 120Kph on hwy now about 2600rpm. Works really well at AMP though.
