Isn't that what people want. Who cares if one car runs 300rwhp with bolt brand X bolt ons. How does that compare to brand Y, that's what matters. I could go dyno my car 10 times with no tweaking and get a variation of 10hp, but without back to back comparison of mods(which I would do if I was marketing a 'performance product') it means nothing.
side note: Did you know that the majority of forum members are NA owners? The 'rich' running JWT's are all based on TT data. just FYI
