Sorry if this is a stupid ?, but someone was telling me today that you could ship the stock LS1 injectors off and have them "flowed" as they called it to 60#. Never heard of this, always bought new injectors for my other cars.

True or False?

You can have them flow matched, which consists of matching identical (or as close to it as possible) flow rates. This is of course you have many injectors to start with.

It may be possible (although highly unlikely) to get them changed, but I believe the guy was confused. If you send your injectors off to be flowed, they will let you know what they flow at, and it they are within a certain tolerance they may be considered "flow matched".

You can increase the flow rates. A sponsor on this site does it. FIC injectors. I just sent my stockers off to get flowed @42lbs for my new setup. I think they can go as high as 50ish. It costs $200 and they are warrantied for a year so it's a good cost effective option.

Worst advice I've read in a long time. My FIC jetted stockers are flowing 42 pounds currently.
