I'm running a Holley Commander 950 Pro. It works great. It's easy to program, compatible with any brand wideband 02 controller, and has great tech support through Holley and over at Chevytalk.com.
I have a spare brand new Commander 950 Pro ECU, software, manual, and wiring harness for sale. It's has the most current firmware and software. And it's in the Twin Cities area!
Here's a link to the Commander instruction manual:
