Well, in my opinion it really comes down to one decision: to daily drive, or not to daily drive?
For example, my car is NOT a daily driver, and does NOT see rain, or adverse weather of any kind. Furthermore, all the research that I had done prior to the the removal of my vsv's indicated that it was not necessary to the vehicle functioning as it should. If I have overlooked some sort of serious problem, please enlighten me, as the issue has yet to present itself in the 6+ years that they, along with the egr, have been relocated to the trash.
Bottom line is that, again in my opinion, if it's a daily driver, it should remain stock, and have every single thing that toyota intended to be on there present and functioning accordingly. Otherwise, it is a non-issue. Take duane, for example. Every photograph of his engine bay I have seen doesn't seem to have an egr present, and given the numbers that his car puts down, I would be under the impression that his motor would be held to a MUCH tighter tolerance than my own. Continuing in this thought process, any problem, however minute to me, would be much more severe to him.
So how MUCH of a problem does the absence of these components really pose, because if it's a big one, I'm probably up shit creek by now...
