Default Fuel Pump? Injectors?

Do you think swapping fuel pump or injectors would be wise when I add the demand of N2O to my fuel ststem?
I have the Maggy fuel pump and currently pressure is 65lbs at idle and 58lbs at WOT. Injector duty cycle is at 92% even with the Meth.

I might as well upgrade the fueling system while were in there so what do you suggest?

Get some 96lb injectors!! At 8psi on my 408 at 6000 RPM I'm at about 43% IDC

I'm still running the stock in-tank pump with the Walbro inline - although mine is different because it's return-style....haven't started to see any pressure drop yet.

trever1 when you find injectors let me know. I've been trying to get a hold of Nelson's Performance. I would like to find 60lb short ones so I don't have to build a spacer for the Radix's fuel rail.

YOU SHOULD DO A PUMP JUST TO KEEP UP WITH THE DEMAN..... AND THE STOCKER ISNT GREAT.

THE INJECTORS ALSO BECAUSE YOURS ARE WAY OVERWORKED.... THEY MAY AS WELL BE AN OPEN TUBE.... THEYRE OPEN ALMOST ALL THE TIME

I have the Magnuson (radix kit) pump already, but am thinking I'll upgrade anyway. Rick said he has a Bosch 420 pump he can put in the tank by modding the bucket system wtf that means, lol.
I'm not sure on the injectors.
