Garner Iowa | I recently purchased a 2006 gmc duramax crew cab, is averaging around 13 to 14 mpg according to display, havent actually checked the milage at the pump yet. But other duramaxes i have driven that have been "chipped" have always shown much better milage and power response. Curious what other people have seen and what they have used to chip their trucks. Also what kind of cost and where is a good place to purchase the equipment.
Thanks,
Rusty | |
