2023 Toyota GR Supra A90 upgrades!

Another Toyota GR Supra A90 tuned in the Whifbitz workshop recently, power went from the standard 366bhp to 564bhp in one hit!

The Supra already had an MST intake kit fitted which makes it sound better under the bonnet but to really get this Supra sounding nice we fitted one of our Whifbitz stainless steel exhausts along with a downpipe too.

We also fitted one of our Whifbitz hybrid turbos which increases power by about 60-80bhp over the OEM Toyota turbo. The turbo uses a larger compressor wheel and modified turbine wheel to increase airflow which stops the power dropping off at the end of the rev band like the standard turbo does.

A Wagner Tuning uprated chargecooler was also fitted, this gives a nice increase in power on its own and will allow the engine to make more power more of the time keeping the intake air temps lower.

We did a full video on the Wagner Tuning charge cooler showing before and after results, see below

Being a 2023 Toyota Supra the ecu is locked so the first thing we did was to to send the ecu off to Femto to get it unlocked and that then allows us to install MHD or Bootmod3 so we can tune it.

We also installed an XHP stage 3 gearbox map which makes the shift speed ever faster and smoother too.

Power went from the standard 366bhp to 564bhp, not bad for a few bolt on mods!

Please see the full video we did below for a more in-depth view.
