HD Diesel Supply Sold Parts with different description than manufacturer recommended
https://hddieselsupply.ca/ I purchased tuning for a 2019 Ram and the manufacturer said it would only work through 2018. They took my money -- ~$2000 and would not let me return parts because they had attempted to be installed and I did not have all original packaging.
They since changed their site, but still refused to return my money, and swore it would work, despite the manufacturer (Race Me) confirming it would not
Terrible customer service. Do not buy anything from them.
