27th Mar 13 Andrew, had the Eco Green box fitted for over a week now, huge power gain & clearly there is an equal helping of Torque as a gain in MPG of 17.8% & 16.3% on two separately calculated trips of Motorway driving covering more than 400 miles. That put the TDV8 Range Rover way over 30mpg. Just like my last box on my van…. Fantastic. Thanks for all your help & advice. If I had one observation the loom could do with being around 2-3 inches longer so then it would go into the battery bay much more easily. Cheers, LES
