This product doesn't quite match the dashs textured pattern and has no set way to mount just sticks to the dash but it's tons better than a suction cup!

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
