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

I was quite sceptical about investing in a Tunit unit, however having now fitted one I wish I had bought one for my last vehicle now having witnessed the difference. I am still trying to get my head around the amount of increased performance and fuel consumption, logic says increased performance reduces fuel efficiency, not in this case it?s simply amazing. I used to average around 36-37 MPG, since fitting the Tunit V-CR I now get 46-47 MPG, and towing well, that?s another amazing change, previous returns of 22-24 MPG where as now I am getting 31-33 MPG, but you really benifit here with the increase torque, outstanding and thank you!
