the way you asked it made it seem like you figured he was venting.

 

I was under the assumption that with a 16g,a 255 pump and 550 injectors would be plenty.Is this not correct,i have the XS engineering super 16g ball bearing and i was going with a 255 pump and 55o injectors to be tuned with an SAFC2.....

 

^^^ that is all you "need" but if you ever want more then the 550s will be the weakest link before you go with a bigger turbo
