I have a 2007.5 Quadcab 4x4 and I have done the deletes egr, dpf, and I have a Smarty Jr. SJ67P and the Cummins runs great. I just wanted to know if there are any different files like ME that I can download on to the Smarty ???
Or should I stay with what I have.( if it isn't broken don't fix it.)

 

If it isnt broken dont fix it is a good motto to have!! I dont think there are more files for the Smarty.. just the ones that come with it. if you are looking for more tuning options, go to an EFI Live.

 

Sounds good Rooster24v,thanks for reply.
