so I'm on a tight budget and I'm looking for a little kick out of my car. I was thinking between a k04turbo or a downpipe front mount intercooler injectors and fuel pump on my k03. For now it's either 1 or the other.

 

APR, or GIAC chip is what you want.

I have a GIAC

 

get a cat delete pipe and intercooler. bigger injectors means a new tune, which would cost another 600$. a fuel pump is pointless as it wont provide you with anything. save up for an elim turbo which require the cat delete and intercooler
