With regards to Len's rolling road graph in comparison to one of my runs:

Uploaded with
ImageShack.usI would comment on the fact that Len's valver seems to barely make over 135lbs-ft of torque and doesnt hold onto this for a decent amount of the rev range, tapering off to under 125lbs-ft before 6400rpm. Contrast this to mine and you can see it holds over 140lbs-ft of torque right from 3.5krpm upto 6krpm, only just dropping under Len's peak torque after 6.5krpm. Even as it hits the limiter of nearly 7krpm my car still makes 120lbs-ft of torque.
This is where I see the difference in the cars, it doesnt seem like they've tinkered much for a remap to make that torque hold on for that much longer.
