Tuning box for mk3 octavia vrs 184bhp diesel. Bought at for €275 and used for 6 months. I've since sold my vrs hence reason for selling this.
Big improvement in acceleration and fuel economy. Economy went from 45mpg to 50mpg even with the extra power.
Connects to the common rail sensor.
Full details below. It's not the bluetooth type.
