Hey Dan,
I know you want to try it out before you decide wether or not I'm full of Sh**. But let me ask you this, did you ask K&N if you could try out there air filters, because you weren't sure if it would be worth the cost &, or trouble? I really doubt it. I'm sure you trust them enough to think they wouldn't sell you something that does nothing. Besides Dan, I'm a fair guy and if I let you demo a system I would have to let everyone be able to have a chance at it.
If you don't trust me, ask HDDP if it workes. I know for a fact, that he knows it works, and he has been just as cautiouse as you. I would say more so, only because we're good Friends, and he is cut and dry. It works or it doesn't work, no second chances. He'll tell you straight out. That's why I respect his opinion so much. He only accepts the best.
