any of those gas savers work for anyone on here?

Every aftermarket "gas saver" is just junk. Just like all of the magic pills to lose weight. If you're really into saving gas, put fuel injection on your car. It will beat a carb hands down for that. Unfortunately, you'll never get enough savings to pay for itself.

Actually, vaporized gas will beat fuel injection, when applied properly. There are several gasoline technologies emerging. HCCI, Spark Initiated, HCCI and Auto Ignition are just to name a few. I go agree that everything to date on the market is a snake oil, but that is going to change.
