I have a 2008 2500 and I just installed the straight pipe with the smarty jr67 with what I thought was the right software. But it has been throwing codes like crazy. Help me please!
What he's trying to say is, if the tuner you have has "US" in the serial # then it cannot load a delete (me) tune and cannot be used for deleting the egr and dpf.
If not then post or pm me your email addy and I'll get it to you.
