Anyone done NOS on their RS5?

Hey, new member here. I bought an RS5 couple months ago, so far I've done engine tune and some gearbox software. Nothing really noticeable.
As a power junky, I'm looking for options to get more power out of my car. But sadly as we all know there arent many options, just a crappy PES supercharger kit.

So I started thinking - what about NOS? It isn't as stupid as some might see it. Sure, you have another tank to refill, but I can live with that. So basically what I'm asking is if anyone has done NOS on their RS5 or at least some other 4.2 fsi car.

As for exhaust and intake, I'm not 100% sure yet. No exhaust system seems to really increase power (prove me wrong please) and dropping 3-5k only for sound doesnt seem too wise. But for intake, I think I will go for the Eventuri one.

Capristo claim 14HP for their exhaust and I can vouch for an increase from the seat of my pants dyno. I have it paired up with the Eventuri intake which gave me an extra 21HP (intake alone) on the dyno.

So there's a possibility of an extra 30HP to be gained from intake and exhaust swap, much more than you will gain from an ECU map alone.

Also, watch out for a supercharger in the next few months.

I'm not sure what you could safely increase the power by using N2O, will you have a map written to correct the fuelling for the extra oxygen?
