I disagree. I think he had some "Quicksilver-ness". I just rewatched that first scene in "X-Men Days of future past" and Pietro is a bit paranoid (checking the license plate of the X-Men's car), he's impatient (running around doing a bunch of things, talking fast), he's arrogant and mocks Wolverine's claws with "It's cool, but it's disgusting". He also has some experience doing bad things (in this instance, theft) like Quicksilver.
