I purchased this for use on my 2008 Mustang GT. I had to download a newer version of software from the Hypertech website before I could install it but that was quix and easy. Once installed I was pleased with the new level of performance that it provided on this vehicle. I installed it after installing a K&N Cold Air Intake system and Gibson exhaust system. This unit tied everything together and the sum total of performance gains was quite impressive, great tuner.

I had a hard time downloading, until I called the tech support, the instructions was simple and worked. I loaded stage 3 setting the mpg increased 15-19 city and 15-24 hwy after it warm-up. I noticed the new life in all around performance immediately.

I had to update the programmer via the internet which took some time because I did not have a normal PC computer with a CD drive. CD update software does not work on Macbook. Other than that small delay, good product.

Installed this in my 2006 Ford Expedition. I set it for 87 octane fuel. It really woke up the engine performance and I am seeing 2mpg better in town and 3 to 4 better on the highway.

Goal: Get a little more performance and have a better driving experience. Results: Truck has a noticeable performance boost and is in fact a better driving experience. Likes: Ability to adjust the shift points, shift firmness, get a little more power, calibrate upgraded tire size (33's) to speedometer and it was simple to install. Dislikes: Required an online update before I could program my truck and I had to look up the optimal settings.

Added power, improved intown/highway MPG, corrected for tire size, however it failed for increasing shift points. Shift firmness definitely improved!!
