  1. Issue with LML - Check Engine Light - S&b intake - Duramax Tuner

    Duramax Fifth Generation: 2011-2016 (LML)
    Hey guys, Unfortunately, I'm needing a bit of help.... I have a 2016 LML. Elected to go with the S & B 'wet' filter intake. I had ran the same brand/style on my 2009 Powerstroke and liked it. Long story short.. Having major issues. Towed my 26 foot travel trailer 3500mi over a 30 day period...
