Question about "higher flow" injectors

[ejfluhr@austin.ibm.com (Fluhr)]

I have a question about the use of the Mercedes fuel injectors.  Are these
used because they flow a greater volume of fuel at a given pressure than
the stock injectors?

Then you must readjust the mass sensor (by the A/F mixture screw) to provide
a smaller amount of lift of the distributor plunger.  The lesser lift
causes the FI head to provide a lower pressure to the "bigger, badder,
better" injector, which the

I thought the turbo engine FI systems had problems generating large amounts 
of HP because the air mass sensor "tops out" (i.e. gets pinned to its
upper limit by the volume of air pushing past).  When this occurs the FI
system provides the max fuel pressure to the injectors, and any more air
drawn past the air flap would cause the mixture to run lean.  Putting
in bigger injectors does not seem to appropriately fix this problem, since
the maximum position of the air sensor would generate a less-than-max
fuel injector pressure.

Obviously I am missing something...probably more than just one thing, too.
I think it probably has to do with the air mass sensor not topping out,
but my knowledge of charged air systems is pretty basic right now.  (I have
been enjoying the information provided in this latest go-around of turbo
wars...what is CI and BMEP???....when I can read around the gruff manner
of the posts.)

Thanks,
