No offense to Brian, because he knows his stuff and I agree with him, but you need to understand reasons why statments are made. Believing anything just because someone told you, no matter who it is, is bad a practice. Even when Jose gives me advice and information, I ask why. Information is next to useless if you don't really understand it yourself.
Anything over 340-350, I would suggest upgrading the injectors.
Stock injectors can support that power, yes, but that is assuming your injectors are flowing full and clean. These injectors are 15 years old. One or more injectors may be flowing really low. With your mods, stock injectors will be ok. But if you wanted to push more power into the 350ish range you should have them cleaned to make sure. If you had a couple bad injectors, a tank of bad gas, a really hot day(with hot intake temps), a boost spike, or a boost creap and your whole engine is fucked. You might be on the edge and not even know it.
And if you're going to have a set cleaned and tested, you might as well test the 440s for future insurance. You could be in the same exact boat later on trying to push 400 with a single turbo. Another set of 15 year old injectors.

Look at this thread for example. If you were gonna push whatever setup you have to the 500hp area, I bet you would want to know your injectors were only 450cc.
Ok, so long story short, I agree with what's been said. You'll be fine with stock injectors. But if you wanted to push more, be careful what you do with unknown 15 year old injectors.
