Our customer returned with their Toyota GR Supra A90 for a little extra excitement. On a previous visit the car was already running an impressive list of performance upgrades:
- DO88 intake kit – highly recommended as it actually gives a power increase unlike other intakes
- Remark exhaust system with sports cat
- Forge chargepipe
- Custom Ecutek tune by us
This setup produced a healthy 397whp (473bhp).



More Sound. More Power. More Supra.
This time, the owner wanted both additional noise and power. We fitted:
- VRSF catless downpipe (race use only)
With the hardware upgraded, we carried out another Ecutek custom remap, optimising boost, ignition, and torque delivery to suit the new setup.
Final Figures
The results speak for themselves:
- 429whp / 510bhp
- +37bhp gain over previous tune
A fantastic improvement and a much more aggressive soundtrack to match!
