Hello all, I just bought a 2021 IS350 F Sport and love this f-ing car. I was starting to think about performance plans and came across this. Was wondering if anyone has used it or is familiar and if so, is it worth it? Thanks.

Definitely some legit snake oil right there.
Unfortunately all the unit will do is trick the ECU into thinking the car is running lean so it will richen the air/fuel mixture.
In theory you will get a tiny bit more power, but say goodbye to any kind of good fuel economy you were getting before.

Maybe check out RRRacing's website if you want some legit power gains: https://www.rr-racing.com/category-s/121.htm

 

Unfortunately, no power gain options for the 2018+ Just yet. We're hoping for later in the year.

My bad...I missed the year of the IS in the OP.

2018 and up.

 

this won’t work for a 2021+ model, already asked VRTuner. They said the 2018+ Lexus models come with ECU protection and can’t be tuned
