[QUOTE="thatJeepguy, post: 1985035, member: 56558"] With the dawning of 8-9 and 10 speed trans now, re- gearing is less of a thing. Also the tq on the ecoboost is even more of an anomaly in regards with people feeling the need. That being said if you do some homework on a re-gear estimate calculator and go to say a 4.88 or 5.13 on 39’s , she’ll go from being decent to being spicy again. Now whether or not the rpm band will be livable on the highway and under 2500 will take some homework. Probably will be about 3500-5k.
