Thumbnail Filmstrip of EFI Conversion Bugcatcher Block Off Plates- to Reduce Air Images
To help with street driving we recomend blanking off 1 or 2 of the outer butterflies. This reduces the amount of air the can flow past the butterfly and tames your engines down so its not too snappy.
These blank plates are simply tack welded into the injector and fully sealed with a fuel resistant sealer.
