So if you look at both there is no way they opened it up and swapped the spring to make it shoot almost exactly what the original fps was, not on such an inexpensive gun.
They put those stickers on so when the customs guys look at it they see it as if it was done by the factory and they have no need to test fire 100 guns they just clear em and send em on their way to the retailer.
Its gonna shoot in the 370 range with. .20's maybe even less tho id say prolly 370 on the money ±3fps
