I was JW what a good programmer would be for gas mileage. he has a 06 duramax im not 100% of the motor trucks stock except for a drop in k&n he just wants better fuel economy. thanks for the input guys.

 

anyone? we were thinking like a edge juice or something? main thing is his egt's i dont want it to get to hot on him. luckily they live in Amarillo now so its pretty flat but i know you still have to watch it. hes not looking for the biggest baddest thing out there. just something with 60-80 hp and better mileage

If i lived closer to him i would do that but since i need it to just be plug and play

 

Would this work?
