Regardless you have to retune your car for it. you will only get the 75 non reliable hp when u spray as opposed to spending a grand on a nice turbo and making that power all day everyday. its cheap power for na cars not cars that are allready turboed. Nitrous also has a faster burn characteristic so you would need a seperate tune and a way to switch back and forth from map to map. If you drive on the same nitrous map when u arent spraying you will loose a lot of hp cruising daily cause you have to retard the ecu to run the nos. There is a lot of reasons no one is doing it.
