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.

 

I guess I will add to this thread. I just installed the same throttle controller today, 11-10-24. It really makes the car much more responsive when you press the go pedal. It is working just as I expected. I have one made by another supplier on my 2023 Corvette and really enjoy the throttle responsiveness on it as well. The throttle controller does not add any horse power to any car, just speeds up the throttle response and makes proceived feel of added HP. On my 2006 SC it is a great addition. Took 5 minutes to install and one road test to determine a setting of Performance 5. Car set to ECT and VSC off makes for a fun ride.
