According to Edelbrock's web page (link - Performance Carburetors and Accessories Introduction - Edelbrock, LLC. ) every new Performer carb comes with an installation and tuning DVD. Also, in their Owner's Manual (link - http://www.edelbrock.com/automotive/...ers_manual.pdf ) the tuning process is spelled out. It's a matter of running it through a strong pass with an immediate shut down (ideally ignition off at speed, coast to a stop) and reading a plug or two, then adjusting jets accordingly. Just my $0.02 on the process.
