Guys
Today I did the test with stock 370cc injectors and I monitor injector duty cicle on Zemulator, remember I have RB26DETT Turbos.
I went up to 14psi and injectors where at 68%, I now my turbos can handle up to 20psi.
Should I try the car to go with more boost?

Thanks for your comments.

I'm not too* familiar with the Zemulator but how was the 68% calculated, was this while driving the car or on a dyno or what?

If your RB26 turbines produce more power than the stock z32 turbines at 14 psi than I will go out on a limb and say something is off. Stock TT injectors absolutely max out around 19psi on race gas, so I'd assume 16-17 on premium. Other factors like what other parts you have do make a difference, but if your skyline turbos are supposed be more powerful at 14psi [I would assume so!] than the stock z32's, I'd be very careful about upping the boost. I'd assume the RB26's would max out the duty cycle around 12-14 psi.

Have you had your car dynoed yet?
