Supposedly Dealers can't detect Spartan. As far as the OP's Bully Dog, sell it, they're Junk!
Would you bet $50,000 on that???

If I was looking for a Tuner, Yes I would.
I've yet to hear of any problems with the 6.4 other than mileage. I think your thinking of the problems associated with the 6.0. Either way, a Spartan, a DPF/DOC delete, and a good Intake will not only wake up your 6.4, but give it ALOT better mileage!
