Dog slow tippers & crew cabs seem to be the flavor of my diary this February, & all 3 have been based in & around Hertfordshire – been programming in about a 35% gain & in most cases seem to get it, torque wise. Should get some MPG feedback in a month or so..
embarrassing is the only way to describe the pulling power loaded i struggled to get 35 mph up a good hill in 3rd now it sits happily at 45mph in 5th without trying .more if i want. totally transformed the van cannot recomend it enough.
