YouTube dyno video Toyota GR Supra custom tune!

Darren’s lovely Jarama edition Toyota GR Supra is back in with us again, this time for a Bootmod3 custom tune and Wagner Tuning chargecooler!

As you can see on the video below, we gained a huge amount of power, with an increase of 125bhp over the Bootmod3 off the shelf map which clearly had an issue with it.

Check out the video below and if you want your Supra tuned or maintained please get in touch.
