i have a stock rev-up motor w/ 36,000 miles on it and looking to spray around 50 shot. I dont race every day or go to the track alot, but will once in a while racing w/ a 50 shot cause any short/long term problems. is there anything i should be looking to upgrade such as spark plug or a tune etc.

Looking at the NX nitrous express import stage one EFI single nozzle system
