Couple of my friends purchased this chips, one for his 2010 BMW X5M and another one on his 2014 GS F-Sport, 2015 VW CC. They say they did notice an improvement in HP and torque as well as MPG. I found the chip for $210, and im thinking of giving it a try once i get my income tax return (yay for the car parts), anyways i could use some MPG since it is hard with Brooklyn to get decent mpg, wonder if any one has any experience with such chips, do they really work and would it be worth it on my RX

 

Don't waste your money. No one has made a performance chip that works for the Lexus computers.

 

Aren't most of not all Lexus ECU's locked?

 

These chips only really work for turbo cars.
