Another stunning Toyota GR Yaris through the Garage Whifbitz workshop this week for a range of upgrades and a custom remap.
We fitted:
- Eibach Lowering Springs
- Eibach Wheel Spacers
- Whifbitz TM Style Carbon Rear Spoiler
- Full wheel alignment
- Custom Ecutek remap




Existing Performance Mods
This GR Yaris already had some great supporting mods fitted, including:
- Direnza Intake Kit
- Japspeed Intercooler & Boost Pipes
- Valvetronic Exhaust System
- GPF Delete Pipe



Dyno Results
As always, we tested the car on our dyno before tuning.
- Stock with existing mods: 224whp / 272bhp — exactly what we’d expect for these upgrades.
- After our custom Ecutek remap: 266whp / 321bhp — a fantastic gain with improved throttle response and midrange torque!
Another great result from a superb little hot hatch. If you’re looking to unleash the full potential of your GR Yaris, get in touch with us at Garage Whifbitz.
