Hi all !
I have a stock TB45E GRX and i want to upgrade the fuel efficiency and power output on it. I知 thinking of going with EFI hardware fuel rail kit. But as experts what can you recommend me ? Any additional changes I need to do ? Also I知 guessing with the fuel rail upgrade I need to add a pressure regulator and a tune up too.
Please correct me if I知 wrong.

Ahh ok.
Probably not a lot you can do with them. They have always been gutless and heavy on fuel. Im not sure whats involved with the fuel rail kit but i would think an upgrade of anything would be better than stock. Not sure about a new pressure reg, but a tune i would say yes too.
