Hello! I have been driving an Antara 2.0 CDTi Cosmo (Automatics) for 4 weeks. At first I was very disappointed with the driving performance. No real power at 150 hp and 11 liter diesel. But now I have had a chip / tuning box installed by my Opel dealer for 4 days. First: VOLLE warranty acceptance by the Opel car dealership!!!! Have everything written, no problem at all. Follow: My Antara goes like “Schmidt ́s cat”!!! Didn’t think it was possible myself, but it is true. He reacts to the commands of the accelerator pedal really great. NO COMPARISON TO PREVIOUS! According to chip manufacturer he should have 25-30hp more. But above all this now higher torque is noticeable! Antara driving is again really fun, not only optical!! Cost: 620€ Unfortunately the spirt consumption remains at 11 liters, shame! But anyway, because now I get enough power for it! I love the Antara! (But only with chip!!!) Many greetings PS: Would I be happy about plenty of statements
