As this forum seems to be mainly US 335i oocupied from a Tuning perspective which is great and very informative, I thought I'd share with you some basic tuning results for the 335D as this is a car that you'll soon have an option to buy.
Latest figures from Evolve ( www.evolveyourcar.com
) indicate upto 355bhp and 730Nm (545-550lb/ft) from a simple remap.......plus the added advantage of 40mpg +. Over here in the UK petrol and diesel prices are high, but the 335d still works out as the better option for those who run up big mileages.

and the graph here showing old remap v new remap, standard figures are much lower(figures are only a guide) -
