One thing I've noticed about IPF's N/A dyno results (on a couple different cars) is that the torque seems to be very close to the HP.
To me that means a couple things. Either the HP is low, or the TQ is high, or some combination of the two. TQ should always be lower on this car than the HP for an N/A setup.
That said, I don't doubt the nearly 400rwhp at all, since that has happened several times with the IPF setups.
