turn up a little fuel

There's a 5/32" allen under the fuel stop sol. & cover, but is very risky to do. This engine can "runaway" if you're not careful. You have to remove the little linkage pieces inside the bowl. I think there's a spring, a small tin-like lever for the shutoff assembly, and the throttle/fuel control sliding plate. There's also a side access cover to get to the adjustment without having to disable the fuel shutoff and remove accelerator sliding pieces and springs. After you take off either cover (and/or the pieces inside) you'll notice a small hole, that's where the 5/32" allen goes. Sometimes it needs to be lined up by rotating the engine. Disable the glowplugs before doing this part! If you slowly rotate it by the alt. you'll see it come into sight. Now turn the allen about 1/4 turn clockwise, less on non-turbo and reassemble it all. This covers the mechanically injected 6.2 & 6.5. :HappyMugs

Those instructions are for 6.2L & 6.5L engines, you cant do this to a Duramax. Sorry bud.

any tuner you buy will increase the fuel to the injectors, as well as change the injection timing, that where all the back smoke comes from
