    you can go to Autozone and pick up a disk to install Mitchells online manuals or go to Ebay and order pirated copies of GM factory service manuals. You might even find a legit Helms service manual online. You will need the wiring diagram to match the PCM tune you're going to use. BTW, 2007 gen4 engine would be in a GMT900(NNBS as some would call it).
