Kolevski one thing I don't agree with is people telling you, you need a tune. The Nitrous will only be used from time to time and if you got a tune it would add the fuel curve at all times this would likely make you run rich. I don't think our ECU will compensate for the use of Nitrous if you tuned it personally. Split Second has a system that I was researching for turbo use that seems rather simple to use and looks like it may be just the ticket, it works very much like a piggy back system to control fuel under WOT and Idle or cruising speeds. In this case you could leave the settings all stock until your ready to use Nirtous then bump up the fuel when your ready to run the car with the Nitrous under WOT (Wide open Throttle). The cars have forged internals so the only damage you'll do is if you don't have the fuel for the nitrous. Hope this helps.
