Hello guys, does any of you have experience with chip tuning at Xantia 2.0 Hdi? Prices, (un)possibilities, it makes sense etc. I don’t need as much final speed as torque – does the tuning bring anything about it? Furthermore, my Citrone has the tick to flash the airbag warning light from time to time. In the workshop no error can be found. Does anyone know this problem? Thanks el feo
