alt Hacker NewsThis was 2008 when they were fighting for titles still (turns out they were robbed and the FIA knew about it and let it play out).
That said I imagine what Jonathan Wheatley would be able to achieve in a task similar to this since he had the Red Bull team maintain a consistent sub-2 second pit stop at Red Bull and he was able to significantly quicken the Sauber one this year.
To play devil's advocate a bit, Ferrari won both championships in 2007 and the constructors in 2008, so it's hard to say they were robbed when they actually won. Massa though, is another story.
