Just wanted to post a quick review of the SC430MODS throttle controller. I bought it for my SC430 but instead installed it on the daily driver 05 LS430. i have to say it is pretty impressive. I like the adjustability and it really wakes the car up. The throttle response is amazing when you want it to be. You can adjust it back when you dont. Easily the best $105 I have spent on this car in a little while.

 

how does it work? never heard of this

 

Yeah I guess I could have explained a little more. It's a throttle controller. Basically it increases tip in it takes out the delay that Lexus put in so that old people wouldn't snap their necks when they tried to accelerate off the line. It makes the car much more responsive.
