IMO, and others, it's not a good idea to spray over 150 through the throttle body, but that is your choice. You will risk the chance of fuel puddling in the intake and a backfire, and unequal distribution.

'Course if trey has the bucks to go fast dfi and dry, along with the fuel system to support it, then i'm sure he can also afford some type of direct port injection for the the nitrous.

Not to seem too f&f style, but a switch on the wheel for each that you can easily reach. 1 stage per gear.
Seems a bit excessive, but i think will end up cheaper. That way if you only do 150, you dont' need a direct port, just 3 nozzles.

Are you joking? I cant imagine trying to operate 3 or 4 momentary buttons while driving. How could you steer or shift? .

Auto 4 stage is overkill IMHO-
thats like 4 50 shots or something.
I'm going to stick to my dry shot (shoot a little 75 shot) till i get a DFI system. I still need suspension and a rear which are cramping this years budget. I already have head porting, valves and a valve job to pay for.
and if someone on the street beats me when i have the 75 shot-
more power to them. 550-600hp is a lot to toy with
edit:
i'd never mess with a momentary swtich
4 WOT switches

Make sure you budget for a new tranny if your still running a 4l60e 
They dont like big nitrous and strokers - too much torque =
Do you have plans to upgrade your fuel system? Or has that already been done. I dont think the stock lines and rails will support the flow you will require to run a 225+ dry shot on your stroker, even with a larger pump or pumps. Dunno for sure - you may want to ask around.
Also, are your rings gaped for spray?
It may be worth your time to stop over in the advance tech section or PM Injuneer. I beleive he's running a 383 with dfi, a dry setup, and a big shot.

A 4 stage could use the same WOT and window switch.
And i was thinking the momentary push button's that you push once and they're on, push again and they're off.
I'd also say that DFI is overkill, you really dont need it.

OK, Heres the lowdown:
Don't bother with a Dry System unless you are spending the BIG money (Mine was well over $3k) for for a Sequential FAST System with Individual Cylinder tuning. A B2B setup (The Typical $1900-$2000 system) just does not give you enough control. Now believe me when I say that going to a Sequential system opens up a BIG can of worms. I really don't think the Aftermarket EFI system is necessary for you. Thats not to say it isn't better, and you would be better off with it, though I just don't see it being a good Bang for the Buck Item. I'm sure you're not revving this thing over 7k, which is one of the primary reasons many guys go to DFI/FAST
In the end you can get what you want with a Wet system. I don't like progressive controllers, and so I would either use 2 stages, or just have 2 different systems. A Smaller 100hp Single Nozzle System (in front of the TB Type). And a Larger Fogger system just similar to Reckless has shown. Multiple stages are NOT =as simple as they sound, So personally I would just use JUST the Fogger at the track, and the Single Nozzle on the street.
Feel free to give me a shout if you have some questions.

How do you like your nitrous controller?
