ok, i have looked around and not really seen an answer. what is max boost on stock fuel? i saw 5psi in another thread. Also the turbo i have has an internal wastegate set at 7 psi. so i need at least that, could i just put another injector in or get 6th gen Si injectors or new, bigger ones? any suggestions would be great, thanks.

I hooked up my Injector dutie cycle meter and went all the way to redline in 4th. It was around 80 percent. So I don't know how much more you can pull out of the stock ones. I wouldn't think you'd want to stress them past 90% because they wont last as long. Am I thinking correctly???

Redline gave you 80% duty cycle? That's stock? Yes, you don't want to go above 90% duty cycle. At least not for extended periods of time.

Well I have a light for every 10 percent, and the 80 percnt light was lit up. I remember reading somewhere that either 80 or 85 percent is the standard for cars so that sounds about right.

I heard that if you get an RSX fuel pump and injectors, you can run 5psi MAX. But you run rich all the time, which bogs down your engine when you arent in boost.
