John ,Honda C-RV 2.2 i-CTDi

Hi Dan. Just to let you know how I am getting on with my Tunit. Fuel consumption has increased on local runs by 5mpg but best of all towing performance is super have changed to a larger caravan since fitting the unit its much quicker off the mark and it flys up the hills can keep in 6gear much longer and is smother. Had to remove the unit when the crv went in for service really do notice the loss of power and acceleration without it. Will keep you updated when I do so long distance touring with the van this year. John Pope

Ben,Nissan Pathfinder 2.5 dCI

Prior to fitting, the Nissan was returning an average of 37 mpg which is somewhat more than the Nissan figures, but I put that down to the area I live in, not much traffic or traffic lights. Since fitting, it is now doing over 41mpg, even with a trailer on, and the pull from 2500 rpm is terrific. It was not bad before.
