Are you looking at the right info? I just pulled up a 2011 335i Xdrive Sedan and just the tune is $750...add about $100 for install, depending on your dealer, and you're at $850-ish, not $1056.
You may have to call around and negotiate a little. I got lucky and priced on my dealer's website, which had a pricing mistake, so they honored it at $704 installed. Good Luck.
