Hello (I'm new in this bmw world
,
I have a few questions for you guys about tuning my BMW E60 525d 197ps 400Nm up to Stage 1 --> 250ps 500Nm.
Specs: 115.000km | Daily driven car.
Is it worth it? Is is it any good or does it do damage to an diesel engine?
Thoughts about doing it and did someone had experience with the same or similar model?
Thanks in advance.
