I am a newbie to the site and diesel trucks. I just bought a 2005 LLY. I have added an air intake and my next step is a programer. I am in no way interested in "high" performance but mostly in fuel economy. Can onyone recommend a certain programer? I plan to go with exaust and a doewn pipe next. If I am screwing up dont hold back and let me know. Thanks in advance for you input and help.
