have you looked into RR racing? I think it’s by far the most popular tune for the IS300/350

You have at least one option with D3performance, however because of the ECU on 2018+ 2GR-FKS engines, hardly anyone has been able to unlock the ECU. I'm personally holding out for a tune from RR-Racing (not available for 2018+ IS models yet), as they seem to be the most reliable for Lexus.

Here's a thread that goes a little more in depth about it, but if you scroll through this board, you'll find several threads about this very topic.

​​​​​​​Is there a rough ETA on when this tune will be available? I read the story about the recent mishaps and the tuning release got delayed as a result
