With research, Russell invested in the DTUK Performance Specialists Digital Tuning Box for the Yaris GR and with another exhaust change it was off to the Dyno, Testing.

Time invested on the Dyno has produced great results for Exhaust Tuning and Mapping of the DTUK Tuning box.

Maps have been specifically manipulated for RS Fabrications and their exhaust design and configuration, in a joint partnership between RS Fabrications & DTUK.

These Maps will be exclusive to RS Fabrications and with DTUK support further testing will be taking place in the future as development continues with the RS Fab Yaris GR.

With a long association with MRC Tuning, results show that is was time well spent.

Russell & Doug ran the Yaris GR, producing 12% gains over the standard Baseline Test that was completed at the end of last year.

Gains in overall power and torque [drivability] were achieved.
