Did you read the whole article and look at the dynograph on page 2?
The torque curve was raised with a 19lb-ft average gain and looks identical in characteristics to stock. The torque curve in the S65 is extremely flat and has two ever-so-slight humps, one at 3,900rpm and the other at 6,900rpm that are almost identical in peak torque.
The tune just gave the 6,900rpm hump a slight increase to be the new torque peak. There is not an erroneous 3,000rpm horizontal shift in the dyno, which was done by Roush Yates Engines -the NASCAR engine building organization.
There was a 24whp PEAK gain, and a 29whp MAXIMUM gain (at 6,400rpm) -which is actually incorrect because there is a
32.84whp MAXIMUM gain at 6,812rpm (303.22whp vs. 336.06whp).
