Hello
I have a 2019 Lexus is 300 and was thinking of getting it tuned with RR racing. tuned alone gives extra 35hp but tuned+ exhaust is 50hp. This may be dumb but what does tuned+exhaust mean?

Thank you

 

Last I saw RR Racing doesn't offer a tune for the 2019 at this time, but it is in the works.

 

Correct, RR Tune only works up to 2017 models, there is nothing 2018+ yet for sale sadly.

I know that there is some D3 Performance tune for 2018+ but never had experience with that and personally I will just wait for RR Racing and their version as I trust them the most with those things.

 

2018+ owners have been waiting for the RR tune for ages, who knows if it will actually be produced…

 

Funny enough it looks like it was released today! I happened to see an announcement on FB a couple minutes ago

daaamn never thought I’d see it!

curious if they can adjust the tune for high flow and Catless headers.

 

Looks like the day has come! I wonder how would their tune work with FBO (Intake, Filter, Headers, Exhaust)

 

Not sure the tune is actually compatible with the AWD 300. Their site is pretty specific to IS/RC/GS 350. And the dyno results they show are only for the 350. Hoping it is though!

 

Just heard back from Rafi. It is compatible. Just placed my order!

 

any update yet?? i am thinking about doing the same.

 

We've been shipping many new tunes out for the IS300/350's.

 

can you provide a little review, worthwhile? do you have a 300 or 350? Did the rev limiter go up to 7200?

it’s a tad disappointing they won’t offer a tune for headers, only reason why im on the fence with Loi…

 

hey just wanted to check how did the tune go and which IS do you have

 

19’ IS350 Fsport 2GR-FKS - I’m fbo so I’m waiting on confirmation if RR tune is fully compatible and will actually utilize my mod’s full potential. I was gonna go Mforce for the pops… Ik ik they can be annoying but I LOVE THEM, however I received an email saying my calibration ID is not yet compatible while there is literally an option for it on their website. So if I would have bought it, I would’ve just had to get a refund I guess? Idk but RR is my next best bet, again just waiting on confirmation from them
