there is a 60 page thread on .org about it, and i think it turned out that nothing was gained by it. i hate to say go read that, b/c i dont think anybody should have to suffer through that bullshit. but, basically there was dyno testing, nothing was gained, and everybody told him how he did the dyno testing wrong. it's like 200 bucks right? fuck, worth a shot i guess. and, i think it has a money back guarantee.
