Recently I visited one website which provides Duramax 6.6 diesel performance parts. I was looking to purchase performance chips for my Duramax 6.6. This is the link to the store https://www.bcdiesel.ca/en/performan...nomy-1-1-1-1-1 . Can you please check this and suggest me the better one? Also, I would like to know whether there is any problem using these chips in our trucks. I have heard that some performance chip may affect the engine. I am expecting your replies. Thank you in advance
