    M4 vs X3 M40i

    I have not posted here for a really long time...life happens I guess. Anyway, I got to take my wife's car today (yes, I drive the minivan everyday and it's a great commuting car), and I was coming home late from work. I was merging on the highway at WOT when all of a sudden I notice someone doing the same that was behind me. I was in the second to left lane and he was all the way left. I notice this guy is not really gaining on me, when all of a sudden, my X3 bogs down and this guy started to walk me. I look at the heads up display and I was doing 133, which appeared to be the govern speed limit. Now, I was in "comfort" but I don't figure that would matter, I thought the govern speed limit was 155. Regardless, the X3 was hanging on with the M4 pretty well, very minor gain by him if any at all while we were both at WOT. I've driven the M4 as well, it is just amazing and stupid quick, therefore I was a little surprised he was having such a hard time gaining on me. All I can say though is good that I governed at 130 or so as there was a cop driving in the slow lane up ahead, if we kept going all the way to 155...well one can only imagine what would happen. Still, pretty impressed with the X3 today, held its own out there, even against an M4. Next up, Drive Event to see how it can hold up on the track.

    Every other manufacturer should give up on building their own cars and just make M3s instead.

    You need a tune for a little more boost and limiter delete. I hear great things about the B58. A friend just bought an M340xi.

    Funny you state that, I've been looking at Dinan and waiting for them to come out with something, can't wait!
