Im planning on buying some DSM injectors for my civic because I'm planning on boosting it. My question is how do you know how much the flow rate is on them? I mean dude said they flow 450cc but how can I make sure that they flow that much and not less cause some people lie? Thanks peeps

 

get them cleaned and blueprinted/flowtested/whatever you wanna call it...

i believe RC injectors does this as a service..

hope that helps,
mike
