i have a programer and high efficiant air filter what else can i do to improve the milage.Have a family so i cant spend a whole lot haha.

 

Depending on how big a family, have them get out and help push. [8D]

MPG gains aren't going to be huge with any addon.

Keep your tires inflated, start off slowly from a stop, combine trips...

 

You can get a better ROI from just airing up your tires, keeping the RPM's under 2K and speed under 70MPH, don't drive it like a gas V8. Power programmers are OK but most peopel can't allways control there right foot on the go pedal so they lose mpg.

 

another good tip is to let the torque do the pulling on the hills instead of laying into the throttle... works great and is good for about .75 mpg or so...

 

Is your programmer a smarty? You could set the speed limiter at 55mph.
