It's lower than that. Mid to low 2,000s, maybe 2,100 to 2,600 is where it's happiest on the freeway.With 5.13 and 37s, I can truly crawl the 4:1 transfercase. I built my rig to crawl - street performance was only secondary. 5.38 would have been amazing offroad but just too low on street IMHO. It is all about balance. I am an automatic.
2700+rpm is not a bad thing in the 3.6 like it may have been in older engines. I am not sure how true it is but read somewhere Pentastar 3.6 hits its optimum power band somewhere around 2800-3000rpm.
