Your times sound like your spinning the tires and not hooking. The first 60ft of the race is the most crucial. After that it gets easy. If you can cut a good 60ft your on your way to a good timeslip. Second of all, yes you can purge your nitrous after every use of it. I purge mine all the time and have had no problems. Third, what was your bottle pressure at..and what was the conditions like? I might be able to give you a better tuning advice for the weather. Weather plays a big role in tuning a nitrous car. For instances like this, Hot and muggy, you either have to take timing away, or add it..add fuel, take fuel away. It's all a guessing game.
