So after a month of trying to get my tuner to work properly, and countless calls and emails and sending tuner back and forth. I tried to do the install with the rep on phone. Not truck won't start and the rep says to call the dealer I bought it from. They won't do anything because I have dpf deleted and my tuner had the delete on it and they gave me an unlock code over phone to have them access somthing in it while I was in truck. They have me another code to enter, that code deleted the dpf removal capabilities and they said we won't give you the code to put it back as it's illegal. I'm in Canada and it's not illegal here. They said to go buy a new one. I'm so ####ing pissed off I'm glad there 1500 miles away from me right now. There inferior service and poor customer service has now cost me another 1000-1500 dollars. #### you h&s. Your garbage pieces of ####.
