Say what you want but no duramax or cummins will run low 13's with just a tune or 1200.00 dollars. One truck has a little more aggressive tune that runs high 12's loaded crewcab by the way.

Didn't all 3 (Ford/GM/Dodge) say and tempering with the egr stuff, particle filter = automatic voided warrenty? , with normal mods (tuner,intake,exhaust etc) you won't have issue with that but they were pretty specific on egr/filter system, any thoughts?
