    Low boost fueling

    Okay, need to understand how this applies to the 6.7L.

    Some reading says it helps to get a large turbo spooling while other says it is about throttle response.

    Both kinda apply to the stock turbo as the truck was a slug, but I don't want to over fuel and soot the turbo vanes during the relearn period.

    I am kinda lost. Any help would be great. Thanks guys.

    And I really need to understand the plus and minuses. No need to just tell me the best.

    Okay, had an issue with surging at low speed.

    So I loaded the non lbf tune. Just as I figured, less throttle response and boost does come on slower, more like stock.

    The sotf values now feel different when doing the relearn.

    Truck also runs leaner and no longer fumes me out in traffic.
