Can someone explain low boost fueling to me

[blk450er]

I see that as an option on my H&S but dont know what it is and how it works?

I think it increases fueling at lower boost levels.

You can use the lbf settings to decrease or increase how much smoke your truck produces when you romp on it with low boost psi.

I guess you could think of it like a safety defuel. The program will lower fuel delivery at lower boost levels to keep smoke down.

I run mine on the lowest setting and it seems to keep my egts a bit lower, but that could be in my head, I'm not positive.

So, its just a smoke thing? Not for running the truck more effieciently?

I think so. My well calibrated butt Dyno can't tell a difference in pick up between the highest and lowest settings.

The mileage seems a little better on the lower settings.

I had no better advice than that, and felt it was a fairly safe reply

I just run mine on the default low boost fueling(3). Some say that the turbo lights quicker with it turned up but I haven't ran anything other than 3 so I can't say whether or not that's true. Running it with the higher levels most likely will dirty oil quicker and cake up the egr valve so I figured right in the middle would be good, plus the smoke is easy to control and as long as you don't stab the throttle right away, I can get into the throttle pretty heavy without much more than a haze at the most.
