I have an 05 Cummings. Which programmer is going to be best for the Buck.

 

There is no programmer available for the Cummings. But there are some available for a cummins! Bully dog, edge, smarty are all good. Smarty has been known to have a very good reputation and I my opinion has the slight edge on the others. I plan on putting a smarty jr on my 05 when money allows. It's all in your preference though.

 

edge will give the most power since you tap the pumps. smarty is good too. stay away from bullydog they love to eat up transmissions.
