Tunit have researched and developed for trucks for over 20 years to produce the very best in performance and economy with engine longevity in mind. Considerable performance gains, which are mainly improvements in torque, keep a truck or van at peak performance allowing you to get the job done with ease. Couple this with an improvement of 12% in fuel economy and the C-24 tackles one of the most expensive overheads a company has, fuel.

Whether it’s a tipper truck, long haul or tanker truck, serious savings are achieved. Although the C-24 is simple to install via original electrical connections, a bespoke tune through a local dealer is provided to achieve maximum efficiency for every vehicle.

The C-24 is successfully run on fleets of all types, worldwide including long haul, tippers, local councils, government, military and police.
