Everyone’ knows that the new 2020 Toyota GR Supra has incredible tuning potential. Someone’s already tuned the ECU…
And the results are exactly what we’d hoped. As a reminder, the “stock” 2020 Toyota GR Supra has already demonstrated that it produces far more power than the advertised 335-horsepower and 365 lb.-ft. of torque. Some dyno testes revealed that the Supra makes somewhere between 370- and 380-horsepower, in reality.
It’s no surprise then that a proper and simple ECU retune has unlocked a further 50-horsepower from the BMW B58 straight-6-cylinder twin-scroll turbocharged 3.0-litre engine. The British tuner, Litchfield Motors, plugged in a new 2020 Supra for a ECU remap and the results are mouth-watering.
The Litchfield-flashed Supra now produces 420-horsepower and 440 lb.-ft. of torque! According to Litchfield, this was an easy tune but also added that there’s loads more potential lurking beneath the bonnet. With the proper bolt-on accessories, 450-horsepower is well within reach. Litchfield is working on co-developing a center pipe and exhaust system with Milltek and Akrapovic to achieve this number.
Knowing Akrapovic and its incredible aftermarket systems, the car will sound incredible to boot.
There are many other mods on the way, namely for the suspension with Bilstein and KW, as well as an oil cooler and eventually, even more power.
The new A90 MK5 2020 Toyota GR Supra not only is the Supra we deserve but will quickly turn into the Supra we want.
