Got mine (320d) tuned about 1 month ago. 203HP / 457NM. 2500km since then with no problem, but I do not use the full torque everyday.
As being also from Belgium I wonder about the Diesel quality ? what's the recommanded brand ? the one to avoid ? I'll do some research and post my findings is any.
FYI, I'm doing 6.9l/100km now.
