	[Van Setten, Tim (AZ75)]  We have tried this in our off road cars
and found that by the time the light goes off, it's too late!  Under boost
you don't want to lean out.  So, what you really want to monitor is the
return to the tank.  When the return line starts to "Dry Up", that's when
the pump is not keeping up.
	If you think about it, the return will stop Before the pressure
drops.  There are some sensors that will trip a warning light under a
specified flow.  Once you know that, then it's easy to boost the voltage to
the pump to keep things going.  
	Hope this helps...Tim.
