As I'm getting my 335d in a few weeks I am now selling my Steinbauer Power Upgrade Box
As most people on here already know it is essentially the same box as the AC Schnitzer one, just with a slightly different tune, it is nothing like the cheap DTUK type 'tuning boxes'.
It will fit any 255bhp (258hp) 30d engine, for full info see here:

Best new price is around £1k
I'm looking for
£500 including postage, or I can fit it for you at my house in Norwich.
Please PM me to buy the box.
