R W ,Peugeot 406 TDi

Thanks very much for your recent service on my purchase of Tunit for my 406. I must say that the help, assistance and service from all of you has been first class and it has been a pleasure to deal with you. The true test came recently when I towed my caravan and awning to North Devon, where I noticed a vast improvement. Thanks for all your help again

Dave ,BMW Alpina D3

After Installation the D3 vastly improved in performance reving like a petrol engine and the extra torque made it pull much harder through the gears.Also it improved the mpg by 4 which is outstanding.Highly reccomended Thanks Dave
