I know a lot of people use dsm 450's...but what other injectors can you use. Would 310's or something be to small? Would it have to be like 440's or something? Also, when do I need to use the resistor box with the injectors?

 

you could run 370 for low boost but just get dsm 450s cuz there cheap

 

Alrighty. So if I run the dsm 450's I need the resistor box right? What is the difference between the blue top injectors...I see some people selling these and some selling regular ones.
