You can honestly do this instantly after you begin the DLC. Get in the helicopter provided and start flying toward Eddie's Villa. Once it is in sight, you will likely notice a blue circle with a plane diagram in it, above a tower in the villa. Fly your helicopter both above and slightly past it. Once you think you are both a good distance above and away from it, (whilst keeping in mind how quickly you descend while skydiving, jump out of the helicopter.
You will do a 180º turn and start falling toward the blue circle. As long as you slow your descent long enough to enter the circle, you should see the "Complete Electrico challenge" notification in the lefthand corner of your screen disappear and the achievement should pop. (Irrespective of whether you crack your skull on the pavement shortly thereafter).
Voilá! One achievement in Narco Road before even the first mission is complete!
