Hello guys, I would put a chip box in my Kappa 2.4 jtd. Not because I am a speed freak, but the car should save fuel then. Unfortunately, my Kappa already has 250,000km on the speedometer, but runs very well and without problems. Only with fuel prices nowadays would such a box pay for itself within a very short time. Now the question to the specialists among you: Is it advisable or should I try it? And if not, why not? Where is hi he the danger? Thanks in advance!! mfg Wolfgang
