18th May 11 Had my box fitted on my new Land Rover Discovery 4 3.0 v6 TDI and to say I’m pleased is a understatement ! On the Trip down to have Cornwall to have it fitted (100 miles) the fuel consumption worked out at 29.83mpg On the return trip back which included a run and blowing off a Range Rover 4.0 HSE the mpg worked out at exactly 36mpg The car now has a lot more torque at very low revs and now does not change down going up inclines, and is smoother to drive, but I was not expecting such a massive improvement between 2500-3500rpm ! The performance now in that range which is between 50-90mph is very impressive and for a 2.5ton vehicle would take a powerful car to pass it. Once again thanks Dave superb neat install into the side pod Steve Rule
