Stay away from EOC Ecodiesel of Canada. I went through them and it was a nightmare! Didn’t receive the parts for 3 months, customer service was rude and disrespectful, and their only solution was for me to pay $300 and they would send a new controller out due to being stuck in customs. Awful company, the worst experience of my life, and would never spend a dime with them.What is the best DEF system delete kit brand?
