So my cherokee has a hell of a time on the interstate. even on flat ground im down shifting more often than not. i wanted to know what some good power adders are. i already have an intake and a TB spacer and im getting a header and exhaust when tax returns get here but i wanna know what some more good ones are. Any ideas?

 

Is the rear end re-geared
when it gets gear high enough you loose a lot of high end speed

 

im only running 32's so i didnt rear gear.
