Hi Bill,
Im a long term customer of yours. And gneerally tune all my own stuff. I'm wondering if there's somewhere I could find a guy that has a 2004 LLY duramax tune for sale. Just looking for a really good fuel economy tune. I have HP tuners and can load it myself also can tune it myself but there's no time. It's getting about 15 mpg with 35s on it. Added H.P is fine but mainly economy. Just figure if there's someone out there I'd appreciate the info. Never done a Forum before really so hope this is done correctly. Thanks Mark Oldani
