The question was originally for the Diablo for the 5.7l for the Rams... but it is not out yet....

 

Do some homework. They have had a nightmare with the Diablo and Hemi's. Released and re-called the tuner on the same day, later released the LX version with promises of the DR coming later. It is well documented that the LX version has blown up engines with anything more than stock parts. The DRvwesion is now going on a year over due and the LX version has a disclaimer that it is NOT to be used with any modded engines! I was fully intent on replacing my Superchips with one when they were announced but now I will not trust the Diablo - EVER!
When I get my finances caught up (just used my truck's mod $ to buy a Grand Cherokee for a daily driver) I'll replace my Flashpaq with the SCT unit so I can get the cam and custom tunes I wanted the Diablo for...
