I got Stage2 tuning for my 325d manual just before easter 2011 and WOW, what a difference.
I just love my "new" car.
It pulls stronger than original all the way from 1400rpm, but pulls on another level from about 2000rpm, and its much more willing to rev all the way to the redline. Still puts a smile on my face when I push on:-)
Keeps the original drivability and also gives me about the same mpg's
My third diesel-BMW tuned by ESS, Fantastic!!
