I've ordered the OBDX Pro VT interface module, so guess I'm committed now to TunerPro and PCHammer, both of which I've also downloaded and played around with. Now I have to order an 0411 PCM. I could get one pre-programmed for the Silverado for $260, or get one for a GM van that will work with just a few program changes for $159.
I'm tending towards the lower priced one, because if I'm setting up like this to do ECM programing, I kinda want to program it. More interesting....
