We've gone through a progression of modifying our 2020 GR Supra and have some solutions available for purchase that we think you'll love for the performance, robustness and cost. We started with a SupraStore downpipe (Catted and Catless) and love the added 30hp and sound from that alone. After this we moved onto what we feel is the best handheld style tuner, the JB4 unit, which is an easy install and can give you up to 80HP with a downpipe. This is a great solution for most owners.
After this we decided to jump head first into flash tuning and we selected the BM3 (bootmod) platform for the software and our tuner Cary Jordan, as he had B58 engine expertise from the BMW world and E85.
Through a hundred hours of tuning and testing, we have what we feel is the absolute best turnkey E85 solution available for the car, which produces over 600hp and 630 lb/ft of torque. This is all on the factory original turbo and fuel system. Flash tuning just isn't for E85, but also traditional gas (petrol) tunes in 91 Octane on up.
