Having returned the stage 1 module with no results and reordered the stage 2 module I am impressed. I drive a Chevy. 2011 Impala LTZ, 3.9 V6. First, my gas mileage increased from 24.2 to 27.1 mpg on the highway. Using 92 octane gasoline. Performance is excellent. Step on the accelerator and keep going. I was amazed from top to bottom. I also added a jet MAF sensor and a K/N air filter. I have been using Jet products for many years. I highly recommend them.
