Works like it says , lacked info on what the lights on the device were for i had to email company for info but not a big deal .

from Derald

Didnt believe that this product would do as well as it does. My friend has tbe same truck that would go into 4 cyliner mode and said it put the engine into 8 cylinder mode all the time and it worked for him and he has told me about this for years. So now i am a believer and a user of the product....

I just plugged this into my truck, it was always a pain in the butt, how my truck responded. No more 4 cylinder, smooth effortless power. No more power lag. I just drove it 34 miles to work, I cannot believe that this is the same truck.
