Tuning Developments Stage 1 Bolt On Performance Package to suit all Toyota Yaris GR Four 2020-on

Tuning Developments have been working with the GR Yaris platform, since its release. Having explored many different options and parts for improvement we have now put together our Stage 1 Bolt On Performance Package for the G16EGTS Engines. This tuning package from Tuning Developments is a must have upgrade package for anyone wanting extra performance without wanting to void manufacture warranty by adding ECU tuning or turbocharger upgrades.

The Tuning Developments Stage 1 Bolt On Performance Package has been dyno proven time and time again to be the ultimate upgrade to unleash maximum BHP and Torque without ECU Tuning, yet keeping reliability at the highest level and improving response and driveabilty.

Before starting on the car, we load your Yaris GR Four onto our in-house Dyno Dynamics rolling road and do some baseline runs on the car to give our operators an insight into how the vehicle is running and performing before adding any upgrades. This is then used as comparison data to look back on after the works are completed and shows you, the owner, the improvement from the car in black and white.

Included with the Tuning Developments Stage 1 Bolt On Performance Package is our popular (and ever growing!) 3inch Catback Back Exhaust System. This is available as Resonated or Non-Resonated configuration depending on your personal preference. Our Exhaust System is UK Designed and manufactured with extensive testing to ensure not only does it function for maximum power increase across the entire RPM range, it also will live with daily usage and high mileage without suffering from reliability issues. It really does bring alive the sound of the Yaris GR Four Engine.

Along with the Tuning Developments 3inch Exhaust System, we include our Tuning Developments Hardpipe Intercooler Piping Kit which increases BHP and Torque throughout the RPM range along with improving turbo response. A K&N Performance high flow drop in panel filter element is also installed, which uses the standard air box and cold air feed to ensure maximum air flow to the G16EGTS Engine. This K&N air filter is also a lifetime filter making the yearly service that little bit cheaper going forward!

Once the mechanical works are completed, The vehicle is then loaded back onto our Dyno Dynamics rolling road to provide a after dyno run to show the increases without any ECU Tuning!

Once completed, you will receive a printout showing power at the wheels and power at the flywheel, against torque at the flywheel. This is done for both prior to works being started and after the works being completed to give you a direct comparison of before versus after.

This tuning package supplied by Tuning Developments is a complete drive in, drive out package and the price shown includes all parts, labour, dyno time and is also inclusive of VAT to make it the most complete and best value for money package available for the Toyota Yaris GR Models!
