Does it really work or is it just a waist of money. If can you tell the difference in gas milage and power.

waste of money. I believe there is a little power increase and fuel milage with the 4.7's but its minimal at that. Bernd has a write up in tips and tricks at www.speedtweaks.net about these.

To each his own I say. I bought one and have it on my 98 3.9 V6 5spd. I installed it the night before I left on a trip to North Carolina. My daily commute to work is a little over 45 miles, one way and I carefully checked my mileage on my daily trip. Before I installed the Tornado, I was getting nearly 19 MPG. On my trip to NC, I checked my mileage and I was getting 22 MPG, both mileage checks were done running at no more than 62 MPH. Now after doing several mods to my truck, I'm running 65-75 on my daily commute and I'm getting 22-23 MPG. The last trip I took to NC after putting in the mods, I got a nearly unbelievable 25 MPG running 65-70 with the AC on. I have found out that if I start getting lead foot, (kinda like that 5 mile blast at 95 MPH up the highway last Sunday, had to slow down for the toll booth) my mileage starts dropping back towards the 20-21 MPG range. I am planning on upgrading the ignition system, a new TB, and headers but thats gonna have to wait a bit.

think about this for a minute. If the tornado really worked as advertised your truck would have come from the factory with one, either that or the oil company would have bought out the company that makes them and taken them off the market. In the real world that's how it works. If you believe it helped you, fine but Dakota29m your milage figures are so really close to what mine is without one that I have to wonder if it was you driving with a lighter foot after you installed it. I drive 17 mi. to work one way, with about 1/2 of that cycle being city anf 1/2 being @65-70 mph and have, over the last 9 tanks of gas averged 19.7 mpg. On a round trip of 310 mi. from home to my son's college and back I get 22.3 ave, summer and winter. My only milage/power mods are brass cap/roter, 2 sizes larger then stock tires, and a cold air intake/ram air system. I have found tho that if you fully top of the tank one time and then only fill it till the pump shuts off the next that it can appear to greatly increase your milage. The best way is to set your trip odometer at zero with a fillup, then use 4 or more tanks of fuel before figuring your milage, as it gives a far more accurate average. Personally I find it hard to believe that a 2 ton vehicle using air conditioning (that alone uses at least 2 and on some vehicles as much as 4mpg)gets 25 mpg. I have a Dodge mini van with over 130k mi a Concorde with over 90K mi. and my Dak 60K mi. and ALL of them use more gas with the air on. Even when new.

My two highest are both 25mpg in Kentucky. I seem to average 23-24 highway. Stop and go city I'm only pulling 18-19mpg though... thats with AC. I don't see how those tornado things could possibly help with that massive beer-barrel intake we have. Any swirl it gives to the air goes away real quick in there.
