I have another tuner question: If I were to buy a used tuner (SCT/5 Star) set up for a 2010 6.2L would it work for my 2011 6.2L? Would the PCM codes need to be the same? Could I get different tunes (cost?)? I want to get your input but will likely pm Mike@5Star.
Yes it'd work, be careful though if it's used an make sure it's unlocked otherwise you'll have to pay to unlock it ( not a huge deal but gotta factor it into the price)
