The entire Strom comes from the Corpse's spine that later was absorbed by Johnny, and after that retrieved to create Ticket to Ride (and subsequently Love Train) a stand Tusk was able to overpower.
If you don't like it we can go for only feats but that would put Gojo in like large building level and Tusk would still scale to Love Train's barrier he overpowered (same ability that pulled the sea towards the US)
