Clear selection

Looking for Improved Power & Torque from your Toyota Landcruiser 100 Series 4.2L Turbo Diesel, then the Tunit Diesel Performance Chip is for you.

This smart device contains a fast 32 bit microprocessor that modifies the vehicles fuel parameters all safely within the manufacturers specifications. The Tunit module operates in a “piggy back” style which means the factory ECU is in total control at all times.  We offer free custom tuning of the module to suit your particular use and application. Most customers achieve a fuel economy saving of approximately 8%, but this is dependent on the driving style, vehicle application & vehicle maintenance.

This module features an easy to use 10 setting manual adjuster to further enhance performance or economy. For added peace of mind we offer a 90 Day Money Back Guarantee, 7 Day Product Support (7am to 7pm) and a 5 Year Product Warranty.

Another feature of our customer service is our “Tunit for Life” program. This module can be reprogrammed for most common rail models free of charge should you swap vehicles. Please ask for further details.
