I can't decided if I should remap or not, but had a run in with what must have been a mapped 325d yesterday and it was stuck to me, I could not pull away at all. So it's got me thinking about tuning again....
My car is on 125k which puts me off a bit but I'm tempted.
Any tuning companies on here, what's the cost ?
Other 535d owners any feedback good or bad?
