i would think that if there was a problem with your engine, you'd hear/feel it coming under boost. But if you switch straight to a shot of nitrous, I don't think you'd have as much of a chance to let go of the button as fast...i have no clue, i've only had turbo'd cars and there are more factory turbo cars than factory nitrous lol so i would stick with turbo, but i think nitrous would be fun to try out
