It all depends on how much power you already make in 1st gear. If the car is a weak dog then I'd spray in 1st, but any 3L and above it wouldn't be worth the nitrous waste and tire wear. Spraying in second if it is a moderate shot and then with a progressive feature would be good and then let it rip in 3rd.
