non turbo ECU upgrade????

[switched]

i have a 1999 3000gt base model(SOHC) 5 speed and will be supercharging it soon, either with Knight turbos (www.boosthead.com) or with www.rippmods.com i haven't decided wich yet (let me know which supercharger system looks looks better to you, they are almost the exact same price)

but what i wanted to know is if anyone knows of a chip upgrade that would work with one of the superchargers. do you know if dynamic racing's ECU, which I believe is G-Force, will work for me???

another thing.....do you think i would get more power with the supercharger and an ECU upgrade(that is if i found one that will work for my application)
or a supercharger, 310cc injectors, headers, and a high flow cat??(i already have a borla cat back exhaust)

please help me out and leave your opinions...thanx
