I don't think it was just in my head, because I check my mpg everytime I feel up, and everytime it was the same around 17 with it and 15 without it. I am not saying they work, ( I have not got one in my ram ), but something was making it change, and this was over 3 or 4 years not 2 or 3 gas tanks.

 

is this a joke????

 

Well, peddler...What exactly are you checking when you FEEL up? Is that why they call you the peddler?

 

That was funny![sm=happybounce.gif]
What do you think I was checking, my tire pressure?

 

i was going easy on gas.

 

Okay, one more thing, apperently you were trusting the trip computer in the overhead console since you only went 15 miles. There are a lot of threads in here already that claim these are of by as much as 20%. You have to calculate on fuel used and mileage driven and then use similar conditions with and without the device. Personally I think you wasted your money. If these are such great devices why aren't the manufactures installing them or something similar at the factory so they can run more TV commercials bragging about their high fuel mileage.

 

i know that overhead is bit off.

I might return it after i did research that tornado gives power loss like HP power loss about 10 percent.
