Improved milage but when I had to go back to stock the milage stayed the same . Point is I am not sure if it did anthing . The one thing I will say is it keeps trans in gear loanger before shifting . Overall 3 stars .

My Hypertech Review (2008 Mercury Mountaineer 4.6 V8)

Reviewed By Hugo G (Livonia, MI) Reviewed for a 2008 Mercury Mountaineer —10/29/2010 6:30 PM

Using the max setting for higher octane fuel, I did notice a change of almost 2 mpg via my trucks OEM display. I also did notice a slight increase in accelaration as well. However, it could have been made a little sturdier. The circuit board inside moves around a fair amount so when I was flashing the computer on the SUV it lost it's connection. Which is how I discovered the unsecured innards of the unit. In short, WHAT A MESS OF THINGS THAT MADE! ! ! Because of that, it also created an error code that I had hard time getting rid of and had to disconnect the battery and reflash a couple of times. After all said and done, I rate it at a B-, includes value added. This is my $.02
