Ive heard somewhere that the post june 06 cummins have a different programming then the pre june cummins, is this true and if so are there programmers that are up to date with this change. Someone said that the post junes have 07 programming?

 

Not only different programming but, a different type of computer. The post 06/06 motors use a CAN BUS type computer which is more data links than hot hard wiring.

There are a couple programmers that are good to go with the new computers. The Smarty is one ( which I would highly recommend ) and I believe the Bully Dog is another. There are others but, they aren't reprogrammers, they're pressure boxes.
