2021 GR Toyota Supra Premium
I have a completely stock 2021 Premium GR Supra. I wanted to check what kind of power it was putting down at the wheels. I was shocked when I saw three runs in a row showing 385 wheel hp with 400 ft lbs of torque at the wheel. The first couple runs showed 365 because the tires were cold and slipping. I also had GoodSpeed check my ECU. I was really happy to find out that my ECU was unlocked and tunable. What I didn't know was if you take your vehicle to Toyota for maintenance or an oil change, they can potentially lock your ECU (if your ECU was unlocked) during a firmware update? Does anyone know anything about this? Anyway, here is the video i have up on my channel. Just thought i would share...
