Disappointed of OV Tune ECU upgrade Lexus GS F-Sport

What about on the GS? Can you squeeze additional juice out of it provided most of us already fill with either 91 or 93(where available)?

We were able to make good gains on 93 octane with the stock airbox and great gains with a cold air intake. The Camry has the same motor that is in the 2016+ GS350. We have a local test vehicle coming in for a tune later this month. We will know much more after that time.

Fairly certain no one has ever hacked the Toyota/Lexus ECU. Good luck though.

Can someone pls tell me if this tune or any tunes out there can improve the 0-60 time? I can see that it makes more power on the dyno sheets but does it actually improve performance in real world driving? Quicker acceleration?
Or Lexus engineers still know what's best for their cars?

Toyota/Lexus play a balance between fuel economy, emissions and performance when the build calibrations for their engines. When we tune these engines, we are looking to maximize torque and horse power. These increases are felt when driving the vehicle. In some cases like the Tacoma down shift tables, their shift points were obviously meant for fuel economy and not performance. We spend time refining what they produced as opposed to trying to reinvent what they produced.

It is interesting to see that the CAI really does seem to push your numbers up. A lot of people on here say that's fool's gold.

The modest improvement in torque may shave off a split second, am keen to see numbers

They should do a drag race of a tuned with CAI GS 350 vs. a stock GS 350. IF it can beat the stock car then it's worth getting it done.
This stock ISF vs. a full bolt-on ISF with a tune shows that a stock car pulls harder or about the same as the modded one. I'm sure the modded one costs a lot $$$ but it doesn't seem to perform any better than stock. Yea probably it has a bit worse reaction time but still, it should be able to beat the stock car easily.

If this works out I can see getting it for the shift points alone. A few extra HP, hey, what's not to like? I'm super interested to see the results when they get the test car.

Hello. I appreciate your response and everything you said makes sense. I was not talking “trash”, and the company itself with owner do really good thing. They correct and adjust that has not been done by manufacture.
BUT!!! Way the articles say and what they actually advertise is different in reality.
My vehicle maintained better then most of the vehicles on the market and it’s 6.7sec to 60 with lunch and traction off as of now.
Before I wrote this article I took another same vehicle, test drove it and it was no.... absolutely no difference.
if you can suggest any modifications that will make a difference I will appreciate it.
best regards

I'm going to pull you up here.
Here's the thing - your car doesn't have an L98 or an LS3 with a free 50 kW and 70Nm to be gained with a run on the dyno. OVR on their website claim an unmodified RC gains 7kW@ the wheels and 18Nm. I've had cars tuned before and it's **** all but to be fair they fairly advertised the modest numbers.
In my opinion the 3-5% increase is going to go unnoticed on our vehicles. I can't speak for the other improvements they claim but if you were expecting a noticeable improvement from that alone, I think you had unrealistic expectations.
The car is advertised as being a 6 second car. Is yours not 6 seconds? You can test it yourself. Maybe needs some maintenance?
Compared to a DSG I grant you it's slower but it should shift swiftly compared to slushboxes 10 years ago. I've heard the 8sp isn't up to par but I don't believe they would have tuned it anyways.
Before you continue talking trash about the company, why don't you tell us whether you actually had it done to your car?
What stage did you go to? Completely stock? New air intake with catback or new downpipes and full exhaust? What was promised? What was their response to your disappointment?

So no difference in 0-60. Better save the money and buy a GSF then.

Either way, they advertised miniscule gains, I'm afraid your expectations were unreasonable. I believe that a <10% increase is unnoticeable to the average driver.
