Hi Ron:

We are both most impressed with the AIRTABS. Stability and smoothness of drive were markedly better. Even in wind conditions or when passing big 18 wheelers, where the CRV shook and moved before, it was as steady as a rock with the AIR TABS on. Also we were getting 485-500 km ( 301 - 310 miles) to a tankful of gas on the highway. Our most effecient recollection from before, and we have over 155,000 km ( 96,255 miles), was squeezing maybe 450 km ( 279 miles) out of a tank. This 7- 10 % saving on fuel is awesome! Thanks for putting the AIR TABS on. We are already getting questions from curious family members and neighbours. Cheers.

The 2002 Chevy Corvette has had the air tabs installed as shown below, as well as under the front splash pan to assist under-car boundary layer turbulence and drag, since December 2006. The car is not otherwise modified. The best highway mileage before Air Tabs was 27 MPG at 75-85MPH constant. After the Air Tabs installation, consistent mileage, over four long (>1000 miles) highway trips, is now 30MPG. If speed drops to 65MPH the mileage goes to 35MPG. No noticeable change in handling because the Corvette is great from the factory.

I must say the day they were installed was July 4th, independence day for sure.

I looked every where for a way to get a little more mileage out of my 1995 Chevy G20 sporty shorty-handicapped equipped van but had no luck until I came across your web site. I was impressed enough to take a chance since I had nothing to loose except a few $'s, anyway after my friend David installed the air tabs I went home on interstate to see/feel if I could notice they were installed plus to see if they were going to blow off. Well sir not only did the Air tabs not blow off but I was not getting blown all over the place when the big rigs would come up flying by me and when you drive with only one hand on the wheel and the other on the gas controls it sure make a big difference when you do not have to fight the drafts blowing you all over. In fact I am more rested when I get out of my van then I have ever been.

On a full tank of gas driving the city speed limits and no faster then 60MPH interstate I got 287 Miles per tank. Most of this tank was city driving.

The 2ND thing I noticed going home was that every time I get to these two places on the interstate my van would shift into passing gear twice, but this time it did not and I had it in cruise control.

3RD I bought my van new in 1995 and I never got no more then 287 miles to a tank of gas. I have a 22 gal tank. Yesterday 7/11/08 I filled up and I had 302 miles to that tank of gas. What that 15 more miles per tank. I think this is great, since I do most short driving at 45 to 50 miles an hour and I was sure I would only see a saving at speeds higher then 55MPH. My weekly driving is to work and back home except two times each week I drive the interstate to take my service dog to Winter Park Florida which is 25miles each way.

Thank Air tabs for helping me go more.
