unless no plastic covers are creating a parachute effect somewhere.... in which case you maybe also losing acceleration. lets face it, you could lose a 1/2 lb on the car based on whether or not you are wearing jeans or shorts....
Long story short, without wind-tunnel or advanced flow software modeling, it's going to be hard to quantify improvement or problems caused by not having plastic underpanels, and for the purpose of this topic, adding panels to improve (reducing) your coefficient of drag (CD).
The simple F=ma is what you are looking at because the F is actually summation(F), where all of the forces acting on the body, in this case the car, are added up. So if your Fd(force drag) is increased, that means your forward force vector is smaller. With that being smaller, acceleration drops.... but it likely only becomes a problem at highway speeds. 0-45 difference is negligible with or without plastic under covers.....

this is the vortex generator i speak of it directs the current to swirl around the back of the vehicle to push down on the rear of the car if placed property and if faced in the correct direction most people put them on straight it is supposed to go / / / \ \ \ or something of that sort i don't remember correctly it was in my class at UTI haha shows how much i learned but anyways its supposed to cause a swirling effect as a truck bed adds but to push down on the back of the car for added traction and stability.
