The Edge Evolution CTS2 is exactly what is needed to amp up the performance or gain extra mpgs. Looks great and easy to use.

most of the people will buy this for more power but i got it for the economy mode is ask for you to use regular (usually 87 octane) so i had to run it on setting 2 until i filled up on 87. Am know running it on setting 3 but with both setting it changes the shift time from factory and with the mile coach it shows me around 23 mpg but it also account for costing with i can do a lot off in WV all and all if you by it sooner then latter it should save you money if you watch the mile coach
