We recently had this 1 of 24 Toyota GR Supra A90 Edition back in the Whifbitz workshop, this time for a custom dyno tune using Ecutek.
This particular Supra is fitted with the following performance upgrades:
- Whifbitz Type 1 exhaust
- Whifbitz sports cat
- MST V1 intake kit
After tuning on our dyno, the car produced:
- 370whp / 442bhp on low boost
- 393whp / 469bhp on high boost

The results were very strong, but the car is now at the stage where it would really benefit from an uprated Wagner Tuning chargecooler. During testing, intake air temperatures were climbing higher than ideal, and with improved cooling we would expect to see another 20–30bhp.
If you would like your Toyota Supra tuned, modified, or maintained, get in touch with Whifbitz today.
Optional shorter version
We recently had this rare Toyota GR Supra A90 Edition, 1 of just 24, back in the Whifbitz workshop for a custom dyno tune using Ecutek.
With a Whifbitz Type 1 exhaust, Whifbitz sports cat, and MST V1 intake kit fitted, the car made:
- 370whp / 442bhp on low boost
- 393whp / 469bhp on high boost
It performed very well, although it now needs an uprated Wagner Tuning chargecooler, as intake air temperatures were getting high. With improved cooling, there is likely another 20–30bhp to be gained.
