Some guy did a 344 HP to the wheels on an IS-F with only 700 miles. They did it in 5th gear (6th is 1:1). That's using Fujita's Dyno. You can search for it at one of the Lexus sites. My guess is that they'll both have similar dyno numbers as far as HP goes but torque will be higher on the IS-F. I'm expecting about 15% loss for Lexus and don't fool yourself.
