Hi, i am a new member and i am saying hi to every body. and i have a question,
how can i make my gs430 more fast by programing the ECU, i have air intak and i would like to know if there is a place that i can program my ECU. i live in michigan, but am willing to go any place in order to program my ECU for more speed. thanks in advance.

 

The Lexus ECU is encrypted, and can't be programmed. If you already have an intake, that's a good start. Look at the Apexi SAFC or NEO to override the ECU and get tuned if you like.

Welcome to CL and happy to have another GS member!

 

thanks for the info, that is really good start thanks again
