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.

I bought the Tunit Advantage 3 for my van and asked Michael to programme it for economy but even though it was set for economy the unit still has a dial of 9 yes 9 settings on it.
My mileage is pretty consistent but I live in a hilly area and my van is pretty loaded so to get 26-30mpg or 320-400 miles per tank BUT if I go on a distance run down the motorway I’ll get close to 600 miles out of a tank!…it’s worth mentioning that I’ve got General Grabbers on the van as well
