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
Was also wondering if u ever tested an M 1 tunnel ram w/ a single 4 barrel top. Looks like it would be bad for distribution, but w/ an 8 injector throttle body, like mine , it has me wondering . ??????
