Duramax Scan Tool (Injector Flow Rate Updating)

I have been searching for a "Programmer", "Tuner", "OBD Code Reader" that will allow me to update my Injector flow-rates when I replace them. I keep reading about EFI-Live, but no-one has been able to confirm or deny if it will re-program flow-rates. I found another article that explains how to do it and that I need a "Scan Tool".

Copied from (w w w . thedieselgarage . c o m/forums/showthread.php?t=1072)
With a scan tool installed, enter the vehicle information and select the following options:
Engine Control Module



Module Setup

Injector Flow Rate Programming


Display ECM & GPCM Inj. Flow Rates


Record all flow rate numbers with the corresponding cylinders from the control modules. Important: When installing a new fuel injector, ensure that the IQA data number from the yellow IQA Data Tag, shipped with the new injector, is programmed to the correct cylinder


⇒ If any injectors are replaced, go to Reprogram Injector Flow Rates parameter and enter the flow rate number of the new injector to the corresponding cylinder. The flow rate numbers will automatically update both control modules.



⇒ If the ECM was replaced, go to Copy GPCM Inj. Flow Rates to ECM parameter and reprogram the ECM. This will update the ECM with the GPCM flow rate numbers.

⇒ If the GPCM was replaced or the flow rate numbers are not the same for both modules, go to Copy ECM Inj. Flow Rates to GPCM parameter and reprogram the GPCM. This will update the GPCM with the ECM flow rate numbers.


⇒ If both control modules were replaced, go to Reprogram Injector Flow Rates parameter and enter the previously recorded flow rate numbers or the numbers retrieved from each individual injector, to the corresponding cylinders.

Can anyone shed some light as to what "tool" I need to complete this?
