s3 Fuel Pressure and %INJ Duty?

[hrb93]

Hi All,

Can anyone tell me what fuel pressure they are getting on a s3 1.8t?

also what % Injector Duty Cycle on a standard car and a tuned/remap car?

Thanks.

ATM: I am getting 87 PSI fuel pressure using factory lines and a AEM 400 (Bosch 044, copy).
Injector Duty cycle 88% on 12PSI Stock motor.

PS: I had the injectors checked and they were 340cc.

standard fuel pressure should be 3bar. (43.5psi)
it is a rising rate regulator so 12psi boost you should see 55.5psi... 87psi is way higher obviously

270bhp region on std k04 injectors is where you usually go 100% IDC

You have way too much fuel pressure/pumps for your lines is what your running pressure suggests
