Martin ,Landrover 3.6TDV8 Range Rover

After installing two tunits in three cars, number three Tunit for the RR Evoque is on order, it has proven very reliable. I sold the last Tunit when I bought the RR 4.2 Supercharged petrol and the diesel user is still enjoying that Tunit in his BMW - that goes back four years! I cruised down to Manchester airport yesterday in the Vogue and recorded 27.1 average MPG! I am not used to double-digits and the petrol station is complaining I am not in there much these days. And that in a 3-ton aerodynamic-brick with a 3.6 V8 engine. Fantastic - and it drive's well too - especially the 'pull' in D6 gear from low MPH. Best results are based on using D6 and setting the cruise for 72 MPH! As they say at Tesco's: "Every little helps!". Best regards, MARTIN BRAGG

Robert ,Rover 75 tourer CDTI

Power, torque and particularly engine smoothness improvements are all very impressive even after the 25 mile drive home from having it fitted.
