I went to SRT's site and they claimed 226hp and 235lb torque. That's basically a 25% drivetrain loss in HP and 22% torque from the manufacture's rating. Is this accurate? Or did Lexus overstate their horsepower and torque readings ala 2001 Mazda Miata?

My personal vehicle dynoed with a 17% drivetrain loss, and a 15% torque loss in torque, although it's not a Lexus, but it appears that most vehicles dyno with a 15-20% loss from the manufacture's claim. I ask because I am thinking of trading in my car and getting either the LS400 or the GS400, so I am not here to start trouble. Please advise...
