My name is Brent, I'm from RI but I'm down in Daytona right now for school. I drive a 99 lightning with a few mods. I got into modify my truck down here and I don't know any trust worry shops up there. But my friend is having a lot of trouble with his diesel, he believes that there is something wrong with his computer but doesn't know. I was wondering if anybody could give me some recommendations on places to bring it. He is in central mass.
