Toyota just offered to buy my car back. Had a new ECU and it didnt fix my issue with my rev power problems. I also had the wiper twitch and my display screen twitch left and right. I had the same ecu and software that are in the 2021s and my car was a 20. I wouldnt tune your car because they will void that warranty. Im personally going to wait till the last model year and hope they worked all the bugs out before i buy another supra. Check my channel out and my vids of what my car was doing.
