Bringing a great thread back from the dead......

I'm looking to get my 2010 LCI 325d mapped and have been stalking forums / RealOEM to try and figure out what actually is the difference between the N57 325d and N57 330d....

RealOEM suggests they use identical turbos / fuelling systems, so all I can assume is that it really is just a de-tune on the 325d.

As for brakes, RealOEM also suggests they both use 330x24 (34116854999) discs on the front, yet the 330d has an option of 348x30 (34116855000) discs.

What then confuses me is that both the 325d and 330d use a 336x22 (34216855004) rear disc? I really wouldn't think that it would have a larger disc on the rear since most of the breaking force comes from the front? (Please correct me if I'm wrong)...

So, what is the likelihood that I'll get close to 300bhp with a tune?

Answers on a postcard.......
