After some research I?ve decided to go with Kempower and I?m very impressed by the results. Local distributor is very professional and there is definitely a profound change in the way the car behaves. It is a "new" car and if gives (even) more pleasure to be driven. Not enough time yet to appreciate impact in fuel consumption but is going to be hard no to step on it, especially now that is responds so well. Top speed increased but response at all regimes is always there. It exceeded my expectations. I sure recommend it to all 525d owners.
