Yes, I did test a tunnel ram against the Wilson intake. The tunnel ram wasn't any better and was a much bigger hassle to use. A lot more weight, more expensive and more complex. All of the Trick Flow tests are on my website in the tech section: Tech Articles | AR Engineering
Andy, I just went thru some of ur tech articles: was wondering how much the dyno headers w/ the long "straight out" primaries are worth over a set of , say 2" TTI`s ??
