True also

Right Again, stay up late reading Probst have you? :-)

Not a thing, your down the straight and narrow olde boy.

Lets look at what EFI guys do for a minute then come back to CIS.
I have been up late reading Corky Bell and learned a few new tricks.
A popular mod for EFI with a swing door type air sensor is to install
the larger injectors, then attache a larger spring to the door to
recalibrate it to the injectors. 

Now what is the "spring" in the CIS system?  These old systems use
hydraulic pressure in the form of gasoline to provide the spring, with 
the various pressures and contollers providing the "spring rate".

This leads me to believe that an adjustment to the system pressure and/or
control pressure will allow the larger injectors to be used.  Caveot...
I HAVE NOT DONE THIS, and have not figured out the details.
Anyone who cares to pitch in their BTDT is now welcome to...
