I think it's kind of critical, because the computer seems to get confused
if too much air is required from the air bypass valve to maintain the
correct idle speed.  I don't know what the "best" idle speed is when the
air bypass valve is disconnected, but I have the best luck with setting
it at almost 1000RPM, and then setting the TPS at that throttle opening.
