All Hypothetical,but would it be possible to get a 6.5 to 7.0 mpg Cat 3406E that makes 700 HP ? In a long hood style truck hauling flatbed loads like lumber. I've thought a PDI or Haney tune and a PDI Big Boss stage 1 turbo. Any other things one could do to hit that magic number or more ?? What about micro blueing a rear end and wheel bearing and maybe a transmission too ? Any ideas ? Oh and let's say it's currently a 2ws 500 HP 3406E.
