Hi Guys. I'm considering a remap for my motor. It's a 2004 E65 730d. I've been reading nothing but great things, but would also like to know if anyone can share their experience around the larger bmw's (530d, 730d).
I'm interested in both performance and fuel economy, as well as anything else people might suggest!
Anything I should consider, i.e. condition of engine, additional issues etc..
