I'm in the process of replacing my '03 330d with an '04 330d. mecahnically the cars are identical, the old car had a remap, not sure what it was, previous owner claimed it had 265 bhp and I can quite believe it, the performance was explosive compared to the new one. The old 330d performed more like my M5 than the new 330d.
The new car is un-mapped, totally standard, what remap should I go for, I'm probably more looking for performance tha economy, the 42-44 mpg the old car did was fine for me.
I'm in North Hampshire (Camberley, so any recommendations for a company that isn't at the other end of the country would be fine.
