Speedytoy, Well when you say basics I have done the following:
1) cleaned all grounds 12 if I remember correctly
2) changed oil and filter
3) fuel filter
4) spark plugs
5) replaced all fuses for new ones
6) changed diff fluid
7) changed tranny fluid
8) flushed radiator
9) air filter
10) paint buffed, waxed
Next is injectors, spark plug wires, ignition (caps and rotors) and A/C compressor clutch, fuel pump... again I am doing all the basics I can think of. If you have any other suggestions I would be happy to here them.
There are a lot more things to replace in the intake to make a smooth running car. Such as 20 year old fuel lines, 20 year old rubber hoses, 20 year old rubber vacuum line connectors, 20 year old throttle position sensor, 20 year old idle stabilizer valve, 20 year old crank position sensor, 20 year old knock sensors.

The N2O will have it's own fuel system, no need for bigger injectors to run with N2O.
But by all means, by the 24's if you are going to buy a sharktuner, but then you are getting into a whole different set of issues.
I really think you need to get the car in 100% stock running condition before you even dream about a power adder of any kind.
The 19's on a S4 will be fine with a X pipe and a sharktuner.
You have to have a good solid engine to start tuning, and unless some one has all ready done your intake there is going to be a lot of things that are going to need to be replaced first.

I am planning on buying a shark tuner soon...
If I purchased said injectors from Rog I would prefer the 24lb'ers as I have moded my exhaust, I am going to introduce nitros and am going to buy the Sharktuner.
And yes Snipers have a plan when it comes to living breathing targets and avoiding detection : ) ... cars on the other hand is a different story, I am out of my element, like an overweight Russian soldier drinking Vodka all day...thus the reason for all the simple silly questions.
I was driving a E92 M3 before I sold it to get my hands dirty with the 928...I have a Lexus as a back up and a 1198R if the backup fails : )

Nitro isn't something I know much about, but extra fuel that is needed when injecting NOS usally comes from an additional set of injectors with their dedicated NOS controller. If you stick in larger injectors in anticipation of NOS then off boost your fuelling will be unecessarily rich.
If you buy a ST2 sooner than later it will quickly tell you which sensors are not correct, and save you money with accurate diagnosis.

I suppose that when the gas flows, it could trigger a new map via the coding plug...

That's an ingenious idea :-) I think I would prefer a dedicated controller for both NOS+ extra fuel. I think the NOS requires large additional fuel ? i.e. very large injectors. Anyway, this is't really a NOS thread ......
