LLY: Bully dog dyno dominator

[carl.swoyer]

I have an 05 lly Silverado 2500 hd lt four door 8 foot bed 197000 miles. Duramax 6.6. My question is the truck gets 11 to 12 mpg Towing a 40 foot landmark fifth wheel. Will the bully dog programmer give me any improvement on mpg. I also have the triple dog .

No, ditch the crappy tuner and either run a PPE Excellerator or get custom tunes from a reputable EFI Live tuner. Bully dog has the worst reputation in the industry for drive ability and economy, not to mention longevity...
