C5 vette nitrous??
Many people love the dry shots, others not so much. Opinions are like buttholes, everyone has one and they all stink....
Dry shot, depending on how your going to do your fueling, your AFR will be dependant on nozzle position relative to the MAF wires or you switching DIP switches on an electronic device that tricks the MAF to add the fuel for the size shot your wanting.
As long as you stay relatively low with you nitrous shot sizes it will work wonderful on your current setup!
You will hear many biased opinions about wet vs. dry, however the dry systems have a bad name because of tuning issues with them. Its never the nitrous' fault (its usually the tuners).... so for ease of tuning and reliability I would suggest wet!
