Justin, I don't even have one but many here have done the installation themselves.
I don't drag race anymore and the "stock" Crossfire performance is just fine with me. But the NeedsWings performance is well documented here on the forum, and anything that can knock off nearly a 1/2 sec. in the 1/4 mile is well worth it. That's why it's the 1st. mod I tell everybody to make when ever they're looking for higher performance.
