Mel Agne (Agnem), has some prototype muti-port idi injectors in the works. Heath (hesutton) will be getting the first set of these "moose misters" at the rally in the next day or so. At this point in time, I believe that they are still in the pre-production phase, but maybe that will soon change...
The only other idi "performance injectors are the DPS "stage ones". If you do a little digging, you will find that they aren't very popular die to their lack of atomization (******* huge amounts of fuel into the combustion chamber).
With some patience and a pocketbook, you can get moosed.
