Anyone upgrading the Horsepower on their LS460?

I'll chime in here for the OP since there seems to be a handful of comments, but not a whole lot of research:
As previously mentioned, the largest power increase is provided via the HKS/Tom's Supercharger and the Rotrex Turbines that Japanese manufacturers sell:
There are other bolt-on modifications such as equal length headers made by other Japanese retailers as seen here:
Here's a clip of how the headers sound on our vehicles:

There is also a bored/larger TB available for our vehicles by Think Design, Craft Tec, and another company that escapes me at the moment:
Cusco/OS Giken also make 1/2-way LSDs for our transmissions.
Bear in mind, power modifications are available for any car. Off-the-shelf or custom, it's a matter of how badly you want the power and whether or not it's worth your hard earned money to spend it.

Those headers sound amazing.
I don't have nearly enough money nor would I want to put my engine at risk by forced induction, but id really give some thought into some headers and intake if the pricing was reasonable.
Thanks again

Anyone ever try gforce performance chips? I used to deal with super chips back in the day. I'll look them up tomorrow. .

Make sure you google up BBB D+ rating, ripoffreport, etc for these guys before buying.

Remind me to PM you about a bridge I have to sell.
Can't really go wrong. I could sell it on EBay if I don't like it....or just toss it away. I pay less for a lunch out with my mates.

Sometimes, you do get what you pay for.
I learned about tuning on my old C5 Vette (Self tuned, supercharged, meth drinking BEAST that put down 602 to the wheels) and it's not something that I'd risk.
Now, $69 for a good bridge isn't a bad deal. I'd spend your money on that! You'd probably get more for your money!
Those headers are Really Nice looking and appear to be quality built. Not too mention that car sounds Great! I'd hate to know the price though (actually, curiosity has gotten the best of me and I would actually like to know, but Please let me sit down first)!

$69 isn't such a good deal if it blows your motor up!.
I've decided against the chip, but only because the hp increase will be un noticeable.

LOL. Why and how would it "blow your motor up"? I'm pretty familiar with tuners and this a very modest hp increase. In general, tuner chips fool the motor into thinking that the air temp is cooler than it is, making the car run richer and changing the timing. This is why I doubt the chip will gain you any mpg, but will give you very modest hp increase.

Adding timing where it's not suppose to be added..
Messing with the AFR (Air/Fuel Ratio)and setting it where it's not suppose to be.
Changing tables that aren't supposed to be messed with.
Messing with cam timing by making it too aggressive,etc.
I'm not sure how tuning a Lexus works (although I'd like to know
), but by changing the IAT (Intake Air Temp) sensor to think that the IAT's are lower, could actually create engine knock (detonation) and pull timing, thus making the car slower. So now you've spent $69 to make your car slower.All of these things can lead to possible damage, if you don't know what you're doing. Not too mention, I Guarantee that if they scan your tune, that $69 snake oil is voiding your warranty!
I don't know how Lexus works, but GM can and will scan your tune for changed variables if you pop that motor. They won't warranty something if they have a loop hole to get out of it.
In closing, by making the car run richer, would make the car run slower. Any stock car that I've looked at the OEM tune is already fat (richer) from the factory. It makes the tune safer and is better for the motor. Making the car run leaner makes it faster (to a point, in that to lean can blow it up by not having enough fuel).
Once again, I'm used to GM cars, and this whole Lexus thing is new to me. So if I'm wrong Please tell me because I'd like to learn as much as I can about this car.
Not trying to argue but it's just what I've found. Maybe you've seen different results.
As stated above, if I'm wrong I invite you (and look forward) to you correcting me.

If one of the parameters is out of bounds (knocking) for anything fuel or timing related and a check engine light is illuminated and the car will go into limp mode by retarding the timing and making the car richer.
It's hard to blow these motors unless you trick the computer.

Everything is relatively the same with the Toyota engines. The newer Toyota aluminum blocks are quiet sensitive to overheating and if that happens it will melt the block. It generally doesn't happen because the cooling systems is quiet good but if you ever have a loss of coolant you need to pull over immediately.

So the names of some of the settings might be different, but the functions sound like they are the same as other cars. Code might be different, but there aren't a lot of different ways to manage an engine.
Thanks again for the info.

Thanks for the info. Every car maker has their own issues with motors and stuff like that. It's good to know that about Lexus' being overheating in case that ever happens. I'd pull over immediately anyway, but it's still good info to have.

The computers that regulate all of the maps and safe guards for Toyota is far more advanced then a stand alone aftermarket computer for performance. The problem is the factory uses a clever encryption that cannot be hacked.
On that note I decided to sell my stand alone for my other Toyota because of the pitfalls of tuning that you mentioned. Most performance driven enthusiasts don't seem to understand this paradox and only see the bottom line not realizing there is no free lunch.

Basic engine technology is shared across all modern engine platforms. Some salient features like the kind of cam phasing technology or injection systems might be different but you can't get around the basic correlation of fuel, spark and air.

I'm new to Toyota/Lexus, but want to learn about them, so I Appreciate the info that you're sharing. Thanks for that.
So it's like a Sprint Booster, except they load it into the ECM/ECU?
