SnowSport magazine (January 2006 issue) has an article about a product that safely reduces the fuel pressure at wide open throttle to increase horsepower and fuel economy. They say that Cat's EFI systems are way to rich at wide open throttle and that a reduction in fuel pressure brings the true available power out of the engine along with the added benefit of using less fuel.

They stress that stock is simply way to rich and that D & D Powersports is simply reducing the flow to where it should be with the device they have developed. For about $250 CDN seems like a simple and reasonably inexpensive way to increase power and economy.

Anyone try this out yet?

I think dawg had one on his sled. There are lots of people running them and from what I have heard, they can make more power,,, but seems expensive to me for what your getting,,, a buddy of mine used the same concept on his by simply putting a jet inline and he plays with the pressure that way. Just have to be careful not to go too far or you will really go too far,,,,
