I guess my reason for thinking the price was very high is how cheaply you can get a map for a d with better results.

My thinking then was, well the N53 engine can already produce 270bhp, so surely its just a "software" issue.
Guess the 3 stage manifold plays a bigger role!

Still be interested to hear if anybody with a 325i has done any kind of performance mod
