what programmer do you guys think is the best for power and good fuel economy? I have a 2006 Dodge 2500HD Cummins. Automatic tranny Bone stock

 

I did my research for what thats worth and went with a smarty jr. It is on the FedX truck for delivery. I'll let you know how it works out......fill out your sig so we know your truck.

 

I went with the Smarty and in all honesty the Jr. would have been just fine. The being said, it's a lot better then the box I had on before. Performance is smooth and quick, does not have a lag, and seems better at an equal setting. Easy to download and mpg's are up a little, still varies due more to conditions and fuel quality. Not leaving a footprint is a big seller to me.

 

I jumped on the Smarty Jr band wagon and love it. Great power a little better mileage, and the price is right. Its easy to use, doesn't take a college degree to figure out. Its all I needed nothing to radical but 100hp will put you back in your seat.
