As we have seen, its extremely easy to spin both sides of the story negatively...truth is both kits have stumbled at the start, but I'm sure both sides will resolve issues. Stillen kit is a tune fix away from making 400+ without breaking a sweat. I have no idea how much the GTM one is supposed to make since no one can post numbers
but if what we hear is true, then they are an intake casting fix away from working fine as well.
