At Hollier Auto Care we are approved to sell and install the Diesel Tunit Diagnostic system. These systems are controlled after being fitted externally to your vehicle’s engine control unit (ECU) and can offer you more power, better fuel economy, increased torque (pulling power) and can even increase BHP by up to 25%.
Diesel tuning can also reduce your vehicle’s environmental impact. Independent scientific research shows that the Tunit unit reduced emissions by 27% and improved fuel economy by 16%. This means that you could save less money at the pump and also reduce your carbon footprint.
These units are available for all makes and models of diesel cars, vans and 4×4 vehicles and all units carry a 3-year warranty.
