    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    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

    Can we get a fix to this? I'm a 'new to tuning' person, and maybe im missing something, but the timing things dont seem to be.. a proper intro.. I feel like im missing something important.
