Do you guys recommend that if I'm getting 550cc injectors with a NIS-tune would the regulator really give me a lot more power someone please tell me what benefits would i get from it if i bought it?

Really? Its a "adjustable" regulator where you can adjust the fuel pressure. Now I wonder how do you expect another fuel regulator magically increase horsepower?

People get it because it is a bolt on solution and it is not too expensive, plus if you upgrade the fuel pump (I hope you have already), the pump usually drives out the stock regulator.

But yes, its recommended to upgrade to aftermarket FPR to ensure stable fuel pressure.

When you put walbro or high performance fuel pump, it will increase your base fuel presuure. You will be idling real rich. Performance come from o2 mostly. You need to figure out on how to stuff as much 02 as possible in the combustion chamber. Fuel is easy.
