"I was quite surprised when I put this module to the test. The performance gains were immediately noticeable and I'm betting that my mpg would go up a few mpgs if I could just let off the skinny pedal. It was a breeze to install, in place in less than a couple minutes. Overall, I would recommend this product, but I would caution anyone to be really sure if you want the stage 1 vs. the stage 2. I bought the stage 1 thinking I wouldn't ever do a CAI or exhaust system, and I was wrong..." —Nicholas O from Draper, UT bought a Jet Performance Module for a 2009 Chevy Silverado, 5.3L V8.
