What has happend to your fuel mileage?? I would love the power increase but can't bear the loss of too much fuel mileage. Right now I manage to squeeze about 280 to 300 miles per full tank. This lets me get back and forth to work on two tanks a week, and I need to keep it that way.

Would something like this be ok to make out of PVC pipe?? I'm pretty good with working on that stuff.
