Hello,

I know a few of us with 3IS 2018+ models are waiting for the RR Racing tune to be available. I asked them yesterday and they are hoping for Spring/Summer.
In the meantime, I was looking at D3 Performance as they have a relatively new product that changes the hp/torque of the ECU.

Can anyone comment on this? I have a 2018 IS300 F Sport (3.5L V6) and would like to tune it up to the IS350 w/ I higher throttle response.

Thank you!

 

I assume with a flash it will affect your warranty if you have one? I'll be looking to do something once mine is out

 

I’m currently using this tune, great product really enhances the f sport+ experience. Highly recommended

 

what do you mean by enhance? Do you feel any power gains?

Funny, i called them earlier this week and they said they are having trouble getting there with it. I also like to know more about this option. Similarly i have a 2018 IS300 F Sport AWD.
