Neil,Mitsubishi L200

We were planning a long drive (approx 1300 miles round trip) to Scotland and prior to the Tunit being fitted were looking at a diesel bill of approx GBP 380.00 for the journey, based on manufacturer consumption info. The actual cost for the journey worked out at GBP 270.00, with the unit set slightly lower than when fitted - but with the vehicle fully loaded. The Highlands presented no trouble for the vehicle, with the extra torque propelling us up slopes with amazing ease, and a much more enjoyable engine noise than the raw tone generated before the unit was fitted. My wife has already brought another unit for her VW, and a friend is buying a unit shortly for his L200 aswell. Cannot recommend these units highly enough.

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.
