As (knova70) says it's an extra set of nozzles plumbed into the intake manifold, and you can then put different size pills or jets into each nozzle in order to keep the fuel equal in each cylinder. In most cases running thru the blower only with the fuel it's not equally distributed and it comes thru hotter than with direct port nozzles.
The tuneup comes by using EGT readers on each exhaust tube to keep the temperature the same in each cylinder, generally around 1100 degrees with alcohol.
