I've just purchased a 06 plate, E90 320d SE.
I apologise in advance if I'm covering old ground, but I've had a quick scan around this forum, but can't find any thread relating to my model & engine size.
I'm looking to get advice on what the best way to start tuning my motor...
ECU Remap, Exhausts, Filters etc..
I'm just looking to get some idea's, potential power Increase? Cost?
Thanks in advance..
