After a bit of research I've decided to get my 320D remapped. Spoke to Jason at BW Chiptune as they are quite popular on this forum and he thinks he can get my 150Bhp up to 200Bhp. I do have some questions being a newbie on this forum as well as BMW owner.
1) Do I need to have a rolling road tune?
2) 50Bhp seems quite a big increase and Im not sure if it makes any difference on economy, parts etc..if I keep it down a notch Eg 190Bhp.
3) How much does the acceleration increase by typically, eg 0-62 mph time?
Any advice greatly welcome, and I will post a review once it's completed next weekend. Cheers.
