I posted this in "The Market" but don't know how many people read it. Anyway, good condition, great deal. $60 and free shipping. I went back to stock setup and lost a noticable amount of power. Missing a couple of the screw covers.
I never had any problems with it. No stalls, good idle... I did feel a slight hesitation a couple times.
I was not happy with the product before I even installed it. Felt it was a little pricey for what you get.
And, I did not think it gave me that much power after I installed it. Now that its off, I can tell you the power gains are substantial and the boost gauge doesn't swing nearly as far as it did.
Since I was originally unhappy with it, and I THOUGHT (but was wrong) it did not give that much power is why I took it off. That along with the debate over the "bends".
