Like the title says I flashed a 2010 g56 cummins with a stock delete for my buddy's Dad an now the truck has developed a rattle/timing knock of some sort. We swapped out every sensor with known good ones an the truck still runs the same. The truck runs to good if u put the pedal to the carpet it takes off rattling an in higher gears will slip the clutch. Things we have checked valve lash is good an according to my scanner rail pressure is good truck has no codes set. My question is has anybody ever seen this before cause we're at a loss on what to do. Also the tuner who we purchased the tune from I'm guessing got shut down or something cause u can't even buy tunes off there website any more. Tried calling sending emails have gotten no response kinda pisses a guy off to spend that kind of money an then get no help. If experts on tuning have seen this before or have an idea on what it could please let's me know cause I might go bald from pulling my hair out.
