I really don't know enough to know what I need or don't need. The truck runs good. I know the guy that redid my harness and did whatever they do did set my rearend for a 3.07 I have a 3.70. Not sure if I need to change that or not. My gas milage looks to be around 12mpg. Not looking for HP or anything else other then maybe better mpg.
