Hello, drive a v70 2 year 2001, with 2.4L 200hp and geartronics. Kilometers currently 105000Km. Have read a lot about chip tuning here. Fa. Heico etc. is not sure if I buy chip tuning or rather a tuning box. Now my question: Does one of you already have experience with Lexmaul tuning boxes? The software can be played from the tuning box via the diagnostic connector. Thanks for your ideas! Dirk.g.
