    We've got a 2013 R500 Scania with 800000km. It drove very flat and constant gear changes to keep it pulling. Dan came up to Milton Keynes one Saturday morning and worked his magic on it.. The remapping has totally transformed the truck. Reigate Hill on the M5 used to be 11/2 gear changes and is now only half a gear. Fuel returns have gotten better consistently by 1-2mpg. From one very happy customer.

    After recently purchasing my discovery 2 TD5 I notice that it was down on power low-end and was slow throughout the gears and was even worse when towing so I got in contact with dan jones @ D.j commercials about remapping. I told him what I want out of my td5 and He was more than happy to help and give advice. Well what can I say what transformed my td5 now boosts and pulls hard low-end and throughout the gears. Would highly recommend
