I'm running a Walbro 450 in my truck. They seem to be the go to fuel pump for a lot of GM people.
Will you be adding a Flex fuel sensor? I know it probably won't gain anything on a N/A vehicle, but it seems you like to tinker.

Re: C5Z Track Toy
I do like to tinker, but the nearest E85 station is 30 minutes away. So that's probably the only thing that I won't be tinkering with. 
Please don't PM me with technical questions - start a thread instead, and send me a link to it. That way I can answer in public, and help other people who have the same question. Thanks!
