Hi,
When we got tsb 07-17-03 in sept 2007, our avg mpg (hand calc) went from 14 to 12. 12mpg is what we have been getting since sept 2007... and that is by driving like a grandma and trying to keep the boost at 10psi on acceleration. I even fold the mirrors in on highway driving, and keep the ladders in the bed instead of the ladder rack.
I'm thinking about getting this newest flash; I can't imagine the mpg getting any worse... but at the same time I wonder if it's possibe to complain enough and get the original firmware put back on... pre tsb 07-17-03 (but not the original flame thrower firmware
)
