I just installed this mod on my car. Installation was very easy. I had to go to my computer and download the actual program to the PPC unit itself and then upgrade my car. It really transforms your car. My car is so much smoother and all my friends say that. Accelaration has increased quite a bit. But the best part is my 3rd and 4th gears. From 80 to 120 my car rockets and it just keeping picking speed with ease. It's really fast. But overall, I'm just happy on how smooth my car is running. I haven't noticed any change in my fuel economy. I think it's a wise purchase.
