[The Punisher]

If the pattern is bad, even IF the flow is the same, it may not atomize the 
same as the others. The position of the injector, and the combustion chamber 
design will also play roles here. If we were talking about a TBI injector, 
that sprayed a bit funny but flowed identical(I still dont see THAT being 
likely) then It probably wouldnt be a real big deal. But in a port injection 
system youre looking for trouble.
