@VF Tuner any updates on the new tune release?

@VF Tuner awesome! Will they automatically be emailed out? Is there anything special I need to do to prepare? Can you also please summarize what's changed in these updated tunes?

@VF Tuner any updates on updated tunes that have the transmission updates baked in? Appreciate all you guys do.

I change my oil at shorter intervals that Lexus recommends. Every 3 -5k. Fun fact 1: If all you're doing is an oil change you can goto a Toyota dealership and get your oil changed for a bit less. An oil change at my local Toyota dealership is $80 vs. $130 at Lexus. Lexus does wash it though...

The only dealer only option I've had disabled is the fake engine noise in Sport and Sport+. Sooooooo much better with the natural sound of the engine. Music also sounds better since the speakers aren't playing the synthetic engine track.

@VF Tuner I'm running the 93 octane OTS tune with TCU mapping. What gains, if any would I see by finding a pro tuner in the Atlanta area?

I've been running mine for over 7k miles. No issues at all. Fuel economy is better and power is effortless. Have been to the dealership for oil changes and rotations and no issues.

I just switched from the tires my Overtrail+ came with to the Michelin Defender LTX M/S2. Night and day difference in ride smoothness and road noise. It's not even in the same universe. The GX550 now rides like a Lexus should. I don't do heavy off-roading so they're more than adequate for my...

Yes. You can clear the codes using the Diagnostic tool in the VF Tuner software.

You hold the plug in place using a trim removal tool that slides between the plug and the white clip. You'd then use the flat head screw driver to depress the locking tab. It will then slide apart. These are the tools.

Oh lord. No. Don't use pliers. You'll want a small tip long screwdriver to depress the locking tab. It will slide apart pretty easily then if you take that approach.

Still all works the same. Just more power and better shifting.

Gas mileage update post 93 octane tune. Today I drove a total of 244.2 miles with 230 of it being highway driving with cruise control set to 76 mph. It was just me in the car on the way to a supplier to pick up inventory but on the way back I was carrying 900 lbs in trunk. I filled up before...
