I was planning to install performance chip for my Dodge Ram 5.9. Last day when I checked in BC Diesel website I found one Dodge Ram 5.9 performance chip of Bully Dog. But one of my friend says usage of some performance chips can lead to engine problems and higher maintenance cost. What about this product? I would like to know about the performance chips of bully dog. Can somebody please check this product and tell me about your reviews?
