Margin for error IMO is much greater on a 150-200 shot of nitrous. Sure you can step it up gradually, but I always found it to be extremely unstable and extremely inconsistent. Blowing motors up usually happens because nitrous IMO isn't as user friendly as a turbo. Nitrous Car you have far more variables.
Correct but if done correclty it can be controlled..
