There are tons of reasons a company makes their motors produce a certain amount of power. My IS350 makes 306hp without turbos. My 335i is 300hp with twin turbos. The Lexus is most likely tuned from the factory to get as much power as they can and still hold reliability. The 335 motor is tuned at very low boost levels (8.5psi). An Evo is, what, 19psi stock? The Supra twin turbos were, what, 7.5psi stock?

I never have and never will own a high performance car without throwing as much power that I can at it (without too much cost or fear of things breaking of course). 10.5psi out of the Xede tune is probably very low compared to what we're going to see down the road. I wouldn't doubt 15psi or so with great reliability. Now, will the clutch go 100,000 miles? Probably not. Will it go 50,000 miles with that much power? Probably. I won't own the car for that long anyway!

And word! :rocks:
