I recently installed the BD power pup Eco (regular) tune on my '05 4x4 and after 300 miles mixed driving have gone from 15.2mpg average to 17.1mpg average without changing my driving style. Pretty pumped to be honest. Anyone else get similar or better results?

Yes and if you add a good flowing exhaust and intake its even better.
Play around with different fuel grades and brands in your area, as that makes a difference too.
I found mine does excellent with non ethanol fuels on any of the tunes for better power and mileage.
Very pleased with the results for it not to be a custom tune such as Uprev.

Is the Bully Dog better than the Superchips Cortex or are they pretty much the same? Or is there another thread that compares the two...I am still finding my way around the site....
