what should the jetting be on a 96 phazer with pipe and gutted air box?

Different brands of pipes require different jetting. Contact the manufacturer of the pipe for recommendations. They may not be able to tell you what it will be with a gutted airbox, but could probably get you in the ballpark. It's best to start rich and go down 1 size at a time until you get to the right mixture. An exhaust temp gauge is good to have when making changes to non stock components.
