'07 LBZ with Duramileage Programmer
I'm running the 80 ECON tune, went from 17.5 to 21.5 hwy @70mph(20@80)
From 10 up to 11.5-14 towing depending on load and grade
getting 24mpg Hwy at 60mph consistant and that is hand calculated, go above 60 and it falls off fast
This setting also gives cosiderable power
The DIC settings are skewed higher than normal, gals used are skewed lower, makes mileage look better
other tunes were marginal
40 Econ was a waste
50 Econ maybe 1mpg
60 Econ about 1mpg
70 Econ about 2mpg
90 power doesn't run as good as the 80 Econ
most likely has to do with the opps , I did not do the upgrades
only one glitch, the EGR throws a code with the EGR blocked.
Well, fix one problem and creat another. Fixed the EGR problem, but now a different code and also mileage has dropped since new code. I think it is time to put this back in the box and ship it back for a refund. EFI is the next step.
