Can somemone tell me about any pro's/cons of adding a performance chip? And possible name brands to look for? I switched from a TA WS6 to my ES, it's got some pep but I want a little more.

Suggestions?

 

I'm surprised their is a performance chip out their for the lexus, but i wouldnt do it. Might void your warranty.

 

What is TA or WS6?

For performance mods, I recommend an air intake. There are other threads already started on the topic. Other then that perhaps some light weight racing wheels. I put some on my ES and it made a noticable difference - reduced the rotational mass and unsprung weight by 10.5lbs at each tire/wheel.

Good luck!

 

A Pontiac Trans Am with the WS6 performance package. A google search would have led you here:

Concerning Modifications to the ECU. AFAIK, no one has been able to crack the Lexus ECU, therefore no performance chips are available.

BTW, going from a WS6 to an ES350 is quite a change in direction
