I can get an RB20de nistune ecu of a mate, apparently I switch 2 wires on the injectors and I'm. Good to go, not to sure though, I've read a few threads a out it. I have been told to get a tuneable ecu to solve this issue and of course just to get better performance in general but wanted a better understanding of what's actually going on.

Sorry, I'm not sure how to delete posts! I'd like to delete my initial post.

I have a series 1 33 gtst, just purchased the car and have a question. Have been told its been rebuilt 40xxx ago and had bigger injectors and bigger fuel pump installed with a standard ecu. it shoots flames.. Like hella shoots them.. All the time. On the jdm cred side of things it's badass but I can't help but wonder.. Is the flames due to the bigger injectors making it run rich?  With it having bigger injectors, would I benefit from installing an aftermarket fuel pressure regulator? If so, what would the ideal pressure be or how would I find that figure?
