Indeed. Care to share specs? Bigger valves? where in the heads was the porting done, and how much larger are the runners now?

I've got the 74mm TB & a splitter in the intake (Pedros Garage). the rest of my intake is 3.2, but I know the TB made a difference. I wonder what an 82mm TB (GT3) would do. I've put this out there before, but my car made 244RWHP with all of the bolt-ons.
