OK guys so let me give you so input on this truck. My uncle has the 2010 X6 5.0 V8 turbo. I switched cars with him for about 3 days (So I can put the performance chip in) This truck has A TON of low end TQ and is an absolute beast!
Yesterday I stayed at the dealership for a couple hours and waited for the tune. After getting the tune I took the car on the highway and the turbos SCREAM after the tune. When the car was stock you could barely hear the stock turbos. Now it whistles like a crackhead with no teeth
. Last night I gave the car back and got back in the M and WOW DID I MISS THE M. Do not get me wrong the X6 is a great "power plant' with that V8 with 2 turbos. However When I got back into my car last night it just felt right. The steering on my M3 is so crisp and sharp. Its amazing how much a difference you can feel just after 3 days of not driving your own car. Anyways just thought Id give my 2 cents on the X6 and would love to own one. BUT IT'S NO M3
