Yes, the graph is jacked up. I think the dip is a shift; pretty sure you can hear it shift on at least one of the runs. Actually, I know you can.
So realistically, it's hard to accurately judge from that graph...however if you take the shift out, it's still awfully "peaky" and doesn't appear to have a very flat torque curve, which is what you want. Even the power drops drastically, which like I've said from my drive, seems to back up what I felt; that it lacked overall power.
Driving around town was just fine, but anything over about 40 it didn't feel all that powerful. With the turbo setup I would have expected a far flatter curve. That's all I'm trying to say (which I often struggle to convey my thoughts into words, especially on the internet).
I just honestly can't wait to see one tuned with a nice flat curve. It could be a little monster I think, with real good power for around town and some decent topend for the interstate cruising.
