    F150 ecoboost - Losing boost.

    Tuning on a truck that starts to cut throttle and of course boost when trying to get over 17 psi. Looks like I may be losing rail pressure when this happens. I have turned up every torque and boost table I can find to get the truck to make more boost. Will the throttle cut if there is a pressure drop?
