4.56 gears, whats your MPG?
Hey guys, I'm going to install a NIB trac loc that I got for super cheap and was thinking about regearing while I have it apart. But I am curious if it is worth my time, my truck is an 07 with a 2.3L auto, looking for a little better MPG. I have BFG AT's on there which were the opposite of good for my mileage, though they are only the 215/75/15's so atleast they aren't too much bigger than my stock tires. I have a K&N filter in and was thinking about getting a different muffler to help the engine breathe but, like I said, going to do a trac loc and wanted to know if the gear change will boost my MPGs.
