I still don't understand why people avoid the tried and true methods to save a couple bucks. There's places to do that and there's places not to.
Edit: I happened upon where he stated this.
That was more about that specific size of Five-O injectors and is similar to the problem ID and DW had when they tried to make an injector in between 1000cc and 2000cc. They all pulled those sizes too due to problems but some manufacturers are doing the intermediate sizes again.
