Ryan,

Likely the TSB you are referring to is the one that details the replacement
of the original "poppet" Central Sequential Fuel Injection (CSFI) "spider"
assembly with the much improved individual injector Multiple Point Fuel
Injection (MPFI) "spider" that is the service replacement when the poppet
design fails.  The service replacement assembly is a much better design,
but I believe it is still rated at the same 22 lbs/hour as the poppet
design.

Here is more information than you wanted -

Say Ryan, I say your previous note about TunerCats software for these
trucks.  I will call you in a week or so regarding a custom program.  I
need to figure out what questions I have to ask you before I take up your
time on the phone.  You have a good web site by the way.  I appreciate the
wiring diagrams being available.

All for now.

I believe the GMPerformanceParts Ramjet PFI intake also has the vortec bolt

pattern.  GM is selling a complete intake kit including injectors, fuel
rail, throttle body, intake, etc for about $1200 from gmpartsdirect.com.

Also, there is a GM TSB out right now concerning the CSFI truck engine fuel

injectors.  There is an "updated" replacement-retro kit that might convert
the EFI configuration to the marine-type setup.  Someone needs to check
into
this.
