Racechip GTS Black for BMW N63TU X5, X6, 750i, 650i, 550i

Description

Adds up to +67 HP, +73 lb–ft torque,  and +20 MPG
Never did a dyno or 0–60 comparison because I don't like to push my car.  I could definitely tell a difference on my X5 50i though, and gained about 1–2 mpg. Only used for a few months and I'm selling because I will be trading in my X5 soon. Original price is 9.
