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

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