I have a 2022 IS300 V6. This car has the 2GR-FSK engine which is the same engine in the IS350 but detuned. I am looking for a tune to make my car same levels as the 350. I’ve been doing some research and narrowed it down to D3 tune, RRRacing tune or getting it tuned by Loi. If anyone has any experience please let me know what you think. What tune would give most gains and anything else I should know going each route.

Thanks everyone!

 

I just got my 16 IS300 tuned by Reflash RD. He does live remote street tune or if you rent a dyno. I prefer that over file being emailed back and fourth.
