Ford 6.4 it's just cooler
I had a Bully Dog 6pos. before my DP tuner 6pos. I may be crazy, but I swear that the Bully dog was quicker?? Got rid of the Bully Dog cause it made the transmission act stupid, but that was when the tranny was stock. Now that the BW tranny is in I doubt it would do the same. Anybody have experience with the two tuners?
