Ebay listing with photos is here:

This is the Stage 2 box for N63 with the "A" type connectors (see photos in link). I sold my X5 so I have no use for this. It will fit any BMW with the 400HP N63 motor i.e. 550i, 650i, 750i, X5, X6 and 5GT
This will add about 40 wheel horsepower to your 400HP N63. You can use it as a Stage 1 box simply by plugging in the two MAP sensor wires - takes about 10 minutes and can be removed very easily with no evidence it was there.
OR you can wire in the 8 extra wires to the ECM which gives another 15 - 20 horsepower.
This is not the current N63 JB4 beta which is $800 however I paid $400 for the Stage 1 and then $350 for the Stage 2 upgrade. I'll send you both boxes.
I am selling for $350 and will ship for free to anywhere in lower 48.
My X5 ran a 12.8 on this tune running as a Stage 1.
No returns due to parts-swappers. Will not fit N63TU engines (typically 2013 and later - please check prior to buying).
Paypal only.
Thanks.
