Big deal! Nobody said it was the best bang for the buck. We just said it was the best (the Hiper is aluminized piping...it WILL rust). And there's no telling that you were running the same boost unless you stared at the gauge. You would have to be running the same boost at the same rpm level at the same peak hp level. And I'm sure that was not taken into account. You are obviously no scientist so you will not convince me that your test was scientific. Sorry!
