Now thats interesting, diva and I ran A test on the tornado. Not much differance 2mpg on the trucks, hard to tell the if the hp was much better, our trucks about 9000lbs. I would like to do A test between the two. With the price of gas and after market parts, that is less than 1/2 price of the tornado. If we can get A couple more mpg this would put us back to what we were getting befor the lifts and larger tires, that would be nice. Diva said she will try one on on the Duster, she has A new cold air duct on her super six setup. 4" plastic tubing to air breather should be A nice place to put it. Thank you for the info Don
