I'm getting about 16.5mpg and two of my buddy's tacomas are getting in the 20mpg range

Yeah I have been getting crap MPGs.  So I have tried to drive more conservatively and I got 20.8 MPG this last fuel up.  Was getting 16-17 MPG with an occasional 18 MPG.  I have not been impressed with the IFS or steering on my Tacoma but upgrades in any direction seem to be about 6k once everything is said and done.
