Hello group,
I have a 2005 Dakota w/ the 3.7L and automatic. I live in Minnesota and in this cold weather my trucks really sucks the gas down, I get about 10.5-11.5 mpg. I was looking for ways to increase my fuel economy. I was looking at the Jet chips and they said since it optimizes the settings of the engine you could see fuel gains. Does anyone know if this is true? Does anyone have any experience with these chips? Is there any other chips/modules I should be looking at? Also my truck is still under warranty, do any of these chips void the warranty, on Jet's website it says it doesn't but does anyone know for sure?
Thanks alot,
John
