I have started to run my car at around 20-21 pounds should i think about getting injectors or fuel pump?

 

You do not 100% need injectors but, a fuel pump would be a great addition along with a tune for the fuel pump. The pump will add reliability and allow you to tune more hp out of the car. On a stock turbo car running 20-21 psi your stock 550's will be sufficient.

If you plan on upgrading the injectors there are some things to consider before picking a size. What turbo do you run now and do you plan on upgrading to something slightly bigger or way bigger later? Are you going to stick with the stock ecu? Are you going to run race gas often, as this usually means you will be cranking up the boost therefore needing more injector. These are all things to consider but, for now if you are on the stock turbo your stock 550's are fine.

Pm me if you are interested in either the fuel pump or injectors or both.

 

I would definetly go with a fuel pump. Have them if your interested.
