Do you run dangerously lean on the inital shot on a nitrous kit?
I just talked to the guy at performance evolution, and he told me to stay away from nitrous and to just save up for a superchager. He said nitrous is dangerous because when the kit is initially activated that the 00-04's with their return less style fuel systems will run lean for a full 3 seconds after activatiuon. So he said that nitrous is like a ticking time bomb and he told me to stay away. I was wondering is this true that our cars will run lean for a full 3 seconds when the nitrous is first activated?

You get a lean spike, but its not terrible. Its just a spike. It doesnt last 3 seconds. It just takes a brief moment for the fuel system to catch up to the demand. Personally I would upgrade to a return system if you are that worried about it. Lethal has the twin pump return setup complete for $900, and it will support like 750rwhp with the right injectors. Also, I would look into an 03 cobra tank to use with it so you dont have to worry about fuel starvation.

With nitrous there is a lean spike at the initial hit. It does not last 3 seconds. For some reason I remember I think I once heard that the lean spike lasts for .3 seconds. I wouldn't be scared to run nitrous. The guy doesn't know what he's talking about or is trying to sell you a supercharger.

Like already stated, there is typically a lean spike when the nitrous hits. There are ways to get around this though.
One simple method of reducing the spike is to run a shorter feed line from the fuel solenoid to the nozzle. This may not completely eliminate the spike, but it can help. Normally, the n2o and fuel feed lines are the same length.
Also, you can get a nitrous controller/WOT switch like this one from Harris Speedworks that will delay the activation of the nitrous solenoid a bit to allow the fuel to flow first.
