The HyperPAC was extremely easy to install. Mounting the display on the windshield is problematic as the sun washes it out badly. A hood would be a good option as would a dashboard mounting bracket . According to the reflashed computer, the MPG increases as the tuning level is increased. My first tank of fuel on level three indicated a 22 MPG average, but manual computations showed less than 20 MPG. Although I am happy with the MPG increase, the difference between the computer and manual computations is troubling. Lack of ability to further firm shifting and change top speed settings is something I only discovered after the fact. Torque converter lock-up is not as positive as needed and leads to disengagement when the terrain is rolling. Overall I am happy with my purchase, but with a couple of minor programing changes the HyperPAC could go from good to great.
