Has anyone ever looked into this fuel pressure riser?....it says that it can add up to 6 hp anywhere from 3700- 5800 rpm.....let me have your opinion on it.....check it out its at gravantuning.com under fuel system.....rksport makes it

 

It's a waste of money started by the Honda crowd (Surprise.). Everyone thinks with more fuel pressure you get more power. Wrong. Don't buy it.
