errr, as long as you have it tuned so that
it doesnt dump too much water, steam causes extream heat/steam and if there is too much it would cause the oil to wash off the cylinder walls amounting to a lot of ring and cylinder wear. Has to be minimal and you wouldnt gain any more with increased water so it's really easy to "over tune it"

Ok, so if I decided to install this for a mileage bump am I pretty safe in doing so? I do a fair amount of highway driving each day and wouldn't mind a few more mpg's as long as there is no compromise elsewhere.
