Since I'm turbo shopping right now, and these two turbos are on my list, I wanted to see how they compared. So I took both graphs from these two threads (

They are pretty close, but not exact. But it shows a good comparison between the two turbos on the same dyno as these cars have almost the same mods. Anyways, just thought I'd share my info.
