I was planning to install performance chip for my GM 6.6L LBZ. A few days back I checked BC Diesel website. I found one diesel downloader of Bully Dog. But one of my friends told me that usage of some performance chips can lead to issues with the engine 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 (https://www.bcdiesel.ca/en/performance-chips-tuners-2
) and tell me about its reviews?
