"Easy to install if you have small hands. It is not complicated to install but space is very limited. Overall I have noticed a difference in performance. I have a little more power off the line. The engine feels like it has a little more get up and go and runs smoother. I did not think it was bad before but like it better now. Too early to say anything about change in mpg. Overall I am satisfied with the product." —Todd B from Minneapolis, MN bought a Jet Performance Module for a 2010 GMC Sierra.
