I'm taking it the first weekend in May.

This is an issue on first start up with a new system. It has to learn the crankshaft position sensor. You need a guy with HP tuners/EFI Live...or a GM Tech II computer to clear that. There is a quick procedure for allowing the PCM to read/learn the crank position - then the light will go off.
You should be able to get your local chevy dealer to do it for you if you find a service writer that is cool and will hook you up with his technician.
