Nowhere does it say you only get one set, but maybe they are reading it wrong about the bottom of this post, it is saying to order only 8 injectors for each VIN, not for the dealer to order 32 injectors and stock them for the next truck. I believe they are reading it wrong and leaning on it.

This bulletin is being revised to include additional model years and revised warranty information. Please discard Corporate Bulletin Number 04-06-04-007E (Section 06 -- Engine/Propulsion System).
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1715916&psdid=271&evc=sm#ss1-1715916">Condition
Some customers may comment on the Service Engine Soon light becoming illuminated. Upon investigation, the technician will find DTCs P0087, P0093 or P1093. Additional customer comments may include a lack of power, a fuel smell on the oil dipstick, fuel in the engine oil, fuel coming out of the crankcase breather, the engine cranks but does not run, or a hard start condition. This condition will not cause an engine misfire. Do not apply this bulletin to any diagnostic other than what is identified in the chart below.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1715916&psdid=271&evc=sm#ss2-1715916">Cause
The fuel injectors have internal conditions that may cause them to return an excessive quantity of fuel to the tank, as well as leak fuel into the crankcase. Due to the return flow and/or leakage, the fuel injection pump may not be able to build up adequate fuel rail pressure.
<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1715916&psdid=271&evc=sm#ss3-1715916">Correction
Important: Before the technician begins diagnostics and repair, be sure to follow the guidelines in Corporate Service Bulletin Number 03-06-04-036 to avoid fuel system contamination.
Follow current diagnostics for the condition the vehicle is experiencing, then reference the table below. If the diagnostics lead to Fuel System Diagnosis - High Pressure Side, follow the diagnostic until the Fuel Injector Return Flow is measured at each cylinder bank return connection (bank to bank).

Start with this SI Diagnostic in the Diagnostic Information and Procedures sub-section of the Engine Controls Section
Delayed Start
Hard Start
Lack of Power
Lack of Power, Sluggishness or Sponginess

Important: If the SES light is illuminated, follow diagnostics for the DTC as indicated with the Tech 2.
Important: When installing the new fuel injectors, lubricate the inside of the fuel injector sleeve with clean engine oil prior to installing the injector. Do not lubricate the injector or O-ring seal prior to installation.
If fuel return flow on either the right or left cylinder bank is above the initial fuel injector bank return flow value, then replace all eight (8) fuel injectors using the Fuel Injector Replacement procedure in the Engine Controls section of the appropriate Service Manual.
Record all diagnostic data as outlined on a copy of the attached diagnostic worksheet. The diagnostic worksheet and a copy of the repair order is to be returned with the removed injectors.
After replacing injectors, perform the following steps:
<LI type=1>Replace the fuel filter element. <LI type=1>Install all disconnected and removed components. Refer to the applicable procedures. <LI type=1>Start and idle the engine. You may have to prime the fuel system before the engine will start. <LI type=1>Connect a scan tool.
Command the fuel pressure control to 160 MPa with a scan tool.
• If the fuel pressure is more than 145 MPa, the system is OK.
• If the fuel pressure is unable to increase to more than 145 MPa. Refer to System Diagnosis -- High Side Pressure in the appropriate Service Manual.
• Be sure to record fuel pressure readings on the diagnostic worksheet.

*Note: The labor time represents a reduction over the previously published time due to unnecessary steps in the repair procedure being eliminated, such as removing the radiator shroud and accessory drive belt. Also, the original add time to replace all injectors was overstated, Finally, the number of diagnostic steps have been adjusted because individual injectors are not being diagnosed. The labor time guide will be revised in the near future.

Maybe this last part is being misinterpreted and they are leaning on this.
