    I have had this on my car for a few months. Extreme fun. Nothing gets in front of you with this. Pretty much as fast as an E63s on the straight line :-) . Later adjustments to the tuning have been fantastic and the car drives very smooth. Highly recommended. I compare my car to a time machine, everything else is in slow motion after this upgrade.
