Paul ,Citroën C4

Had my tunit fitted same day I bought my new C4 especially noticed the increase in performance. Fuel economy can exceed 60mpg on a long run against mid 40s.

Martin,Seat Leon 1.6

Have now had my Tunit Advantage for 2 and a half years, many trips to Spain and the box has paid for itself many times over, improved fuel economy, more torque and eliminated flatspots in pickup, teamed with DPP, achieve more than 60mpg round town. Have now done 50,000 miles, will be getting the Advantage 2 on my next car in March. Excellent service.
