Isn't that alos a bit strange. Isn't 4th gear at 7000 RPM like 100+ on an STI? That is some fast spinnin rubber in a shop.

And last but not least, it is a Dynojet...
I have read through most of the thread (and I got paid to do it!), and apparently the flattening of the torque curve is artificial. It was introduced through tuning to reduce the shock on the stock clutch when the turbo hits.

Yes it is a dynojet, the guy who did the tuning claims a stock STi does around 240, so I guess it is about 10% higher than Nate's dyno
