I have been thinking about fuel injection upgrades for my TQC.
After I install the S4 turbo, and get some more flow I may try to 
extend the fuel system keep from leaning out.  On Nov. 3, a Bosch Part 
number 0437-502-015 was  posted as Mercedes V-8 part with a higher flow
rate.  I.E. at a given pressure you get 20-30% more fuel delivered. 
My concern was about linearity across the range of engine operation. 
The way the system works now, the air mass sensor/ fuel distributor 
varies delivery to try to hold stochiometric ratio, with O2 correcting.
Ned says the stock air mass sensor is fully saturated at something 
between 250-300 HP.  Thus he sells a bigger one, but it lacks O2 sensor.  
New injectors can be had for less than $200.00.  A fuel distributor 
is much more $$$, (3x-4x).  My concern with the injectors is that you 
will be trying to run richer as the flow increases, and you make the O2 
sensor dial back the pressure.  Then at WOT, the system is delivering max
fuel, insensative to flow rate when the air sensor is saturated. Doesn't
seem ideal, but maybe thats the trade off.

Has anyone bought these, or heard of someone doing flow rate measurements?
Does Bosch publish fuel delivery rates versus pressure for the various
injectors?  Is anyone on the list running with these injectors?  Thanks
