Have you tried resetting your ecu? A lot of times the cars computer adapts to certain driving habits and compromises peak performance.

I would suggest resetting the ecu and seeing if there is a change,

I've driven both....You are right....LS430 does feel more responsive and quick for its size

I think you disconnect your battery for about 30 minutes.

Remove the negative battery cable, hit the brakes once to make sure all the power is off, and allow the car to sit for 15-20 minutes. Reattach the cable and you should be good to go!

Your radio will lose its presets but you will not need to put in any codes,

I have both cars and I feel like my SC goes faster than my LS. Although, my LS is an 01 like yours my SC is an 05. I don't know if there's a difference from your 02, but I def think my SC feels faster than my 01 LS

Yes

also, make sure the transmission is set to power mode. makes a big difference.

I own both currently, 05' LS and 06' SC....I am with CALBOY76 and 97-SC300, the LS "feels" quicker.

The LS definitely feels way smoother and more responsive, it is one of the question that still puzzle me, since supposingly they both got the same engine and tranny, both the engine and tranny got the same price tag. They got the same final drive ratio too, but Lexus don't publish the gear ratio, my feeling is they are the same though.

I am guessing is the computer programming. Lexus want to program the SC to feel more sporty, I think in the process of making it feels sportier, they made it less smooth, that is my theory.

Maybe because the LS is smoother and more responsive, it "feels" quicker.

I think in reality though, the SC is a quicker car, it is 200 lbs lighter, and I do think the SC gather up speed quicker, just "feels" slower.

Feels and actual is 2 different things

02' and 05' SC should be the same mechanically, really the only big mechanical change was the 6-speed tranny in 06'.

SC may get up to certain speed quicker than an LS....But LS definitely is more responsive...As soon as you hit the pedal...it downshifts right away while SC has a bit of delay which makes it feel slower.

Isn't there a design difference in the headers?
