Questions & Answers for Tunit Advantage3 Performance Diesel Power Upgrade (6 Wire)


Who are Tunit?
The first Tunit product was created in 1998 to improve performance and fuel economy for Diesel Engines. Since then the product has been developed continually to work with Governments, Armed Forces, Companies and of course individual drivers to improve drive, performance and economy even further. The original Tunit and its more updated big brother the Tunit Advantage is an interactive computer that is a step beyond methods such as opening up engine computers and altering physical engine components.

How does it work?
The Tunit Works by careful and safe Modification of signals Sent from The Engines own control computer to the engine. Accelerator, air, fuel and load readings are accurately used to calculate improved signals that are delivered to the engine with digital precision and speed. The result is a smoother power and torque gain. More power is delivered throughout the rpm range and more importantly lower down were needed for improved take off and acceleration. This produces progressive power gains without sudden surges or dropping of power. The turbo or other mechanical parts are not directly altered, so there is no strain on this or other engine components.

What is the warranty period on Tunit products?
Each Tunit Advantage comes with a 5 Year Product Warranty. For all vehicles 5 years old or less a 1 Year engine and driveline warranty is also provided for your peace of mind.
