Kieth ,Volvo S80

Good improvement to smoothness of volvo D5 (not the smoothest diesel in the world) and noticeable low-mid range power. Very happy with improvement.

Hi Jamie, Just a short update- I used to get around 450kms on a tank @ 65-70mph. Now I have done around the same milage at the same speed and the tank is just under half full still! The power is phenomenal, and as I said previously the drive is much more enjoyable. Kind Regards
