Ive heard from my friend that the TL's handling suffered from the excess power so they lowered the hp. but then i heard from others that it was bs and they just put that on paper but the engine is the same.

theyre still the same engines but rated using the "new SAE" standarized test. this tests just standardizes some of the varibales for hp/tq ratings. most japanese cars have taken hit on their hp on paper but theyre still the same cars.
with the TL, i think on 2006 models and up, they incorperated the new SAE standard and also because of severe torque steer (esp. on their manuals) they made some changes to combat this issue. i forget what they did but i think it had to do with lowering initial torque... i dunno i forget.

but its interesting the new 07 nissans 3.5 VQ engines are rated at 255hp (if its true what your friends saying) because they were one of the last to hold out on incorperating the new SAE standard. which means the 350z and g35 VQ engines with better breathing isnt too far off for the 330's 255 (which has a pretty damn good tq curve)
