4000 RPM...boost?

01-20-2007, 12:06 PM
I have a 2007 X3, manual, and I have noticed that (in all gears), under medium acceleration, the car really kicks in at EXACTLY 4000 RPM. Those of you with a manual tranny, try it and let me know what you see. Try 3rd gear, and just accelerate moderately, not too fast at all. I was testing this today, and when the car hits 4000RPM, it feels like you stepped on the gas.

Just wanted to see if others have noticed this, or it is adapting or something.

No in my 2005 2.5 Stick. Smooth all the way to the limiter.
