And let net tell ya.....40 down low is a MASSIVE difference just cruising around.
Now you're on the trolley. It isn't about the 2 at the top, which I think we can all agree is meaningless. It's about the 40 extra lbft at 2500. There's an even wider gap below that, and then it narrows as revs increase, becoming equal right around 3500 rpm.

I've driven it with premium before, there is no way in hell there was 40 ft/lbs more torque at 2500RPM, or anywhere.
It didn't feel any different at all... because it's the same engine. Same computer, ECU. compression, etc. If Lexus really wanted to retune that, spend the money and resources to give LX owners a meaningful difference wouldn't they give it more than 2hp??? There is no way I'm missing 40ft/lbs of torque at 2500RPM because I'm not running premium. No offense but that's absurd.
But I'll put some premium in tomorrow and run a few tanks.
Did you not watch the video of it going up the big hill and not even cresting 2k? That was in 2nd gear start, too. Gearing, yes, whatever had something to do with it.... point was it's a strong engine with lots of torque and that video confirms it.

Don't "my god" me. I was told I'm losing 40lb/ft of torque, when I've driven the truck with premium before and it felt the same.
Go to the link on IH8MUD and read stories for yourself. It's about split even. Again, not one report of a damaged engine from regular fuel.
There are plenty of talks about tunes.
The bolded makes zero sense. We can talk tunes etc etc but the 5.7 makes 383 horsepower on premium, up from 381 in the LC and Tundra. So how is that "way more horsepower"?

Premium vs Regular is the #1 most controversial topic I’ve seen on car forums. Tens of pages people arguing back and forth, no one ever convincing the other party they are correct.

It's actually not a very complicated issue. Higher compression engines, and many engines with turbo chargers require premium gas due to it's higher ignite point, while regular gasoline has a lower flash point, and the higher heat generated by performance engines can pre ignite the fuel causing engine knock, which is why they pull timing. So if you drive a Toyota Corolla, you don't need premium.
Better yet, check the owners manual, and save yourself a big fight with your fellow forum members

You don't either vehicle with the 18 year old 5.7 that went into hundreds of thousands of trucks asking for 87, yet I can't find one instance of engine damage caused by cheap fuel and I've looked.
And nobody's fighting, I'm not. I just said it's absurd to suggest I'm missing 40ft/lbs of torque at 2500 RPM. I've run premium before and felt no difference. It's got a full tank of premium and we switched cars this week so I'll be driving the LX.

It says 91, but as I've said I think that's BS.
I will let everyone know if the drivability is different now, remember guys I've owned it 3 years now....
I'd like to move on, duly noted to those who think I'm wrong.
