So what's the difference between the two models?
Both products utilise our own custom engineered RevSense software, making obtaining astonishing economy and performance gains easy as 1..2..3!
Packed with a powerful digital microprocessor chip our system monitors your engine millions of times a second, learning from your driving style and making small tuning adjustments to your diesel engine's fuelling dynamically, ensuring the additional power is applied exactly when needed (unlike less sophisticated tuning boxes) and always within the engine manufactures design limits.
Users wanting the benefits of chip tuning with the minimum of fuss should choose the standard model, which will in most cases work fine out-of-the-box, giving a good power and economy boost whist still providing 9 different maps so adjust our diesel tuning chip to suit your driving style.
For advanced users wanting that little bit more, we offer our 'Professional' version, this model uses our unique Tri-Band adjustment system allowing the user to add additional power gains at three distinct parts of the rev range. Low down for maximum economy and further up for performance.
This powerful "bolt on" feature gives the user extra control over the RevSense system allowing experienced users to fine-tune the performance and economy gains even further.
Tri-Band adjustment delivers total control over the character of the vehicle and is ideal for users who tow trailers or caravans wanting extra power or economy or the performance user wanting the ultimate remap device!
