Regearing will always help with large tires but it isn't a cheap thing to do. The electric motor torque works very well around town. It does as well as the 3.6 around town. It was definitely helping the motor as my rpm was low leading to better mpg. The performance was excellent (handling 37's) and not even in league with anything but the diesel and 392. I have zero complaints but some obviously expect better mpg, I guess, even going 80 mph.I am wondering if you would get much better performance and economy with changing gear ratios. As the 4xe pure-electric side of the system is only 130hp it maybe struggling with the 37's.
