Sorry Sir i quite disagree, what tune will bump the HP on the 550I from 445 to 560 ????? , unless your talking about spendig some good $$$ you can beat an M5, or maybe if it gets up to 500hp it will beat a stock W219 but not a W218 sorry, i will just have to see it to believe it , we all know AMG always won the HP war , or whats next the 2013 E550 TT tuned will beat a E63 5.5TT ???

2014 BMW 550i
And put a few bucks into the (especially 2014) 550i tune and it's bye bye C219 CLS63 or even new C218 CLS63. People here are underestimating what a tuned 550i is capable of, and I'm not even talking about the 2014's with the N63tu motors with 450 HP that have raised the power bar against the direct M-B competitors.
