I would double check that the vacuum lines on the TVIS are connected properly. I rebuilt the engine in the 85 MR2 I used to have and screwed this up when I reinstalled the engine. It seemed to run fine, but it would fall on it's face before redline. After I fixed the vacuum lines it was fine. I think the secondary butterflies weren't opening all the way how I had it hooked up.
