The only way a belly pan should cause lift is ground effect compression, where the quantity of air that goes under the vehicle can't accelerate quickly enough and "piles up" under the car.

Other than that, it should actually create a lower pressure zone under the car that will induce negative lift, albeit a small amount, due to the acceleration of flow that isn't obstructed.
