Tuning options for X5 35i

[riyute]

Hi all,
I am comtemplating on getting a 2011 X5 35i.
I have been reading up, but unable to find a highly recommended or preferred reflash.

Can someone point me to the right direction?

Juicebox from Burger Motorsports? Works for me....

JB supposed to be piggyback right? Anything that does ECU reflash?

If it's n55 engine - Cobb.
