I just bought my first diesel and I'm loving it. I have a F250 with a bulletproofed 6.0 at only 130k. It has an older bully dog programmer in it but i don't think its working right. Im not seeing any changes no matter what setting its on so I just ordered the new Bullydog Programmer to make sure I'mup to date on that. The problem is there's an error code on the #8 injector. I know its bad or at least not working correctly. I was thinking about replacing all of them with bigger injectors but I want to know what else will be needed if I do. I dont know anything about diesels yet. Can anyone make any recommendations as to what course of action I should take to get the most out of this rig? Its sluggish from a stop and sometimes it runs better than others. It doesn't smoke at all but the former owner admitted to me that he didn't keep up on oil changes regularly. Thats probably why an injector is bad. He said he just spent $3500 having it bulletproofed but couldn't tell me what that really consisted of. Maybe someone can explain what that meant as well. I would really appreciate some solid advice before I commit to anything. I have a little over $2k to work with. Thanks guys!
