Its a hotly contested issue.
Some say they have removed it and found no less of low RPM torque, some say that it has suffered.
I'm of the opinion that Toyota aren't idiots, and they stuck it there for a reason.
I'm rebuilding my 3SGTE at the moment and I'll be leaving the TVIS in. Partly because my engine won't be extreme (only around 280-290HP) and I will be running standard ECU and turbo.
The GT4 is a heavy car, so in my view, for a road car, you need every bit of low end torque you can get to retain good driveability.
If I was aiming for 400HP+, with aftermarket ECU and turbo and maximum flow capacity was my goal, then I'd gut it. Probably cause it wouldn't be a daily driver so its behaviour at less than <4000rpm wouldn't concern me.
