Thomas L from Phoenix, AZ said, "Although my '04 Cavalier isn't out to break any world records anytime soon, after installing my Jet Performance Module I can feel the difference. One word of advice, probably more for the GM 2.2L & 2.4L crowd, the installation instructions where a bit vague with where and how the connections where to be made. But after successfully having it all installed with a big dose of time and patience, there is a noticeable seat of the pants push (not plastering you to the seat mind you) & with a quicker climb of the speedo. After all is said and done, it really feels as though my car is running smoother and better than before, along with returning better fuel economy.All in all, and simple enhancement to any vehicle."
