I cant disagree with your statements. This just goes to show you that every truck is different I have an '07 5.9 same as you and mine reacts in almost the opposite way with BD compared to your findings with smarty.
Only time will tell about the custom tunes with BD. BUt for right now I know I can fuel deeper in the rpm range then I can with smarty.
by the way....Did you make that grill insert yourself? If you did what did you use?
