tuning a vg30e to handel boost with nistune

hi guys im pretty new to all this i have a vg30e terrano with a sc14 supercharger set up. top mount intercooler rising rate fuel pressure regulator and upgraded maf and injectors. im not pushing for crazy power but a bit off boost for the beach dunes and some mud will be good. i have a question since its been na i was thinking mabey the fuel and timing maps from the vg30et would be a good base to start from? or is that completley wrong as itd be nice to hear it start and run on its on steam before i take it to get a proper tune. im aslo doing the efi tuning course at the moment to get a better understanding. also the sc is set up with the same amount off boost as the the stock vg30et 8lbs
