I know theres alot of topics about how safe is nitrous but is there really any company thats more safer than another or are they all pretty much the same? I know if you use 200 shot on a stock engine...it doesnt matter what company you are using. Not being safe means you will destroy your engine. But do any of them have any safety measures in place where if the engine starts to run lean...it'll stop the flow of nitrous and hence...your engine will be safe?

 

Nitrous is nitrous. If you install it wrong or do too much of it without the proper fuel and tuning, it will blow your engine. Doesnt matter which brand you use.
