No, but i will get some.
this would allow you to run antilag as you would have the 5ht injector to run it off??
dont you think the engine will get flooded when all opening at the same time. Check haltech and AEM, they have standalones management that control secondary injectors.
my engine builder came with a nice idea for the furture
make indeed a second fuel rail into the manifold but,
don't hook it up to your normal fuel line, give it racing fuel from a second tank.
controled by a EMS set to a specific situation.
as mentiond before smaller injectors give a better fuel mix.
as some ppl know im v intrested in doing this
