My only perks for nitrous is that a) you can run regular everyday and not worry about turbo issues b) flick a switch and its still a good kick in the pants. Your right though ill be hooking up my aem wideband and fuel/oil as well as a window switch and nitrous pressure gauge, it adds up but I enjoy it, no spool etc. Also on my old hemi you could slam a 200 shot on it with a nitrous tune then switch to an 87 tune for daily driving. 650hp daily driver is sweet....haha....even if it's only 450ish on the streets.
