18 months ago I went to the Atm Chiptuning dealer in Cazin, Bosnia and Herzegovina. First of all, my car came to the Autolab company for repairs, no one knew why the car had little power. After spending a lot of money and nerves, the car was still weak. Luckily for me, the director of Autolab fixed everything and the car went as it was when it was new. It is a Passat b5.5 96 KW, 5 speeds, 130 hp / 285 Nm. Then Autolab did chip tuning at 170 hp / 390 Nm. I am very satisfied, we are going to Stage2 soon. Thanks to the director of Autolab who has a huge knowledge of electronics, mechatronics and mechanics - I can say the best car expert I have met.
