From the setlists I've seen from the US tour the setlist is absolutely identical right down to the position of the solos between songs, other than occasionally Momento Mori was played and Love You To Death wasn't.
What did you see that was different?
Besides which, after the Maiden tour the US had with Dio and Motorhead supporting while the UK suffered Funeral For A Friend, no complaint about tours, setlists or anything else about any band is valid from an American
