Would like to see some feedback on 350 owners that have the RR or OVD tune. The forum is filled with 200t/300 owners feedback but not much or any of current 350 owners.

I am on the fence in purchasing the less expensive OVD tune but I like the fact that RR is working on the supercharger for our cars and will discount the kit if we already own the tune.

The main perk I see is the 7200k or the 7400k redline. Maybe a faster 0-60?
Another perk would be one shift to get to 60.
I have heard several RC350 exhaust videos of that new redline and it is sweet.

RR-Racing for sure. I'm the Co-founder of Lexus Performance in Saudi Arabia and have worked with Rafi and Simon for tuning too many IS350 RWD. Believe me it's the best tune out yet.

And don't forget that they OWN the same car and more R&D is going on + they working in development the SC KIT for our cars

Also the best customer service, if you have any questions they will respond to your questions ASAP.

Good look

Mesh, could you write some review or feedback of the tune? No one seems to get very detail for these tunes and there are just too many unanswered questions.

I would like to know its drivability, comfort, transmission logics (shifting points and harshness of shifting), driving the car in auto mode, difference in Eco/normal/sport modes, 3rd party dyno graph, dyno graph after the 6.4k rpm, low-end torque compared to stock, and possibility of professional dyno tunes.

Hey Mesh, I think you are the only active member to have tuned the is350 with headers. I am only interested to see if the transmission slips at top end and what your 0-60 looks like. I have seen your Dyno vids and they do look like the transmission hold the gear maybe an extra second or two before moving up in gear.

I know that in normal, Eco, sport and sport + while in drive the Transmission continues to shift at the normal point until you move the transmission selection to manual mode and in sport or sport + where it starts shifting at 7200k or 7400k.

The only thing RRR need to fix is the Slip after 6400. They will fix it when they have the TCU Tune which will they have it soon.

But the car pull faster and harder than before

Love the tune

I have faith on Rafi&Simon

Can you elaborate on the slip?

Mesh704

Yes sir ( see pic attached)

Is that just a tuning thing? Cause the trans should be identical to the IS-F trans which takes more power.

Nice whp numbers. What's your wtq read?

Mesh704

I think it was 276WTQ

JGO

The dip doesn't look too bad. Can you feel it while driving?
What about the power dropping? I thought it was supposed to hold power to the new limiter?

IS200TFOWL

I like it.

You should do a small shot of NOS and see what happens

I believe that the OVTuned option is better than the RR-Racing tune. This is the first time I've seen the slip issue as no OVTuned 350 owners seem to be experiencing it, judging by their forum posts.

I'm waiting on their SC KIT to be released!!
