Yes... but there is no real advatage of the dual VVT-i feature in regards to performance.

The addition of the VVT-i on the exhaust side of the engine was intended for better emmisions.
I believe the little extra power from the new TS comes from the increased displacement plus probably better flow technology within the engine.

On the other side the new upcoming engines with Valvematic do provide better performance due to the cams lift feature.

The same 2ZR engine but with valmatic has an extra 10-12 hp at the top of the power band. And that is in it's stock form. Those engines tend to benefit alot from bolt on mods (I/H/E).
