To get a TRUE comparison, we need to put a S4 on the same dyno on the same day as a 340i
Regardless, I'm not sure what you expected from a 335i, but isn't it only 306hp stock?
I came from a B7 S4 (340hp) to a 328i and a 340i. The 340i blows my S4 out of the water with supposedly less HP. There is NO WAY the 340i is only 320hp unless the S4 drivetrain loses that much power from crank to wheel.

From my experience its better to see whats what on a 1/4 mile. Seems the the 340i is running 12.4-12.8, my stock b8 S4 ran a 13.2 some guys can get it up to 12.8 but its rare and they have manual trans. The B9 has an additional 30 hp and ran a 12.8. I am sure with the right conditions they can get that down to a 12.6. The 340 would be about as fast maybe a touch faster than the B9 S4, with the MPPK it would be much faster.
