I don't think I'll be dynoing it with a 1ZZ as I'm more of an economy driver than a performance one. The manifold is not only designed for the 1ZZ throttle body, it was also designed for a 1.8 engine so I don't think it would make that much difference in an normally aspirated application. However, a forced induction situation would be a completely different story. Even at the tooter's best +4hp at 5,600rpm that isn't nearly enough to be detected in actual driving. And remember that's at wide open throttle. Most driving is at partial throttle, where the difference between the tooter and stock manifold is too slight to feel. We've been running it on our daily driver Yaris for over 2,000 miles now and it works just fine. And the stock air box really quiets down the intake.
