This new device attaches to the TPS and reduces the voltage (within the paramaters) to decrease the amount of fuel injected into the cylinders. It is even coming out for big trucks. Does anone have any idea how it can be marketed? I have used this on my car for almost 6 months, and it works. I have put it on a variety of vehicles and they all show gas savings, it varies with engine size and driver habits. check it out at
