2020 Toyota GR Supra A90 – Back for Remap!

/ by

Our customer’s 2020 Toyota GR Supra A90 returned to us for another visit on the dyno after fitting a sports cat to replace the original Toyota catalytic converter. With the new hardware installed, it was time to make the most of the upgrade with a fresh custom tune.

We carried out a custom remap using MHD tuning software on our in-house dyno, optimising the calibration to suit the freer-flowing sports cat and the car’s existing modifications.

This GR Supra is already well-equipped with some quality performance parts, including an MST intake kit, Wagner Tuning chargecooler, and a custom exhaust system — all working together to help the B58 engine breathe more efficiently.

Last time the car was with us, it produced 410whp (488bhp). After the latest tune with the sports cat installed, it’s now making an impressive 424whp (505bhp). That’s a solid gain and a testament to the effectiveness of combining high-quality hardware with a proper custom calibration.
